Facebook Complains About The Performance Of Latest Intel And AMD Processors

Facebook has been complaining about how their latest racks of server from AMD and Intel have been unable to provide them the performance improvement which both the companies have been claiming. Facebook Vice President Jonathan Heiliger said that the engineers at Facebook have hardly seen any performance improvement and energy saving   from the new processors from Intel and AMD which both the companies tout. Jonathan Heiliger said, “The biggest thing that surprised us … is the less-than-anticipated performance gains from new micro architectures. The performance gains they are touting in the press, we are not seeing in our applications.”


AMD responded to Jonathan Heiliger’s comment and said that there server class processors are the highest performing and the most energy efficient CPU in the market. AMD also said that there can be a performance difference because of the difference between the Synthetic Benchmarks and Real World Applications. Nigel Dessau from AMD also said that its possible that Facebook is not able to see the desired performance improvement because its application uses more of Java and PHP instead of C++.

Personally speaking, Facebook first needs to optimize their code for better scaling. The current Facebook API says enough about their codes’ scaling efficiency. Newer processors does not always tend to increase the performance if the code/software itself is not able to scale properly.

Intel Launches Celeron E3200 And E3300

Intel today released 2 new ‘Celeron’ branded low-end dual core processors namely the E3200 and E3300. Both the processors run at 2.4 and 2.5GHz respectively and have double the L2 cache of their predecessor at 1mb. Both the processors are built using the 45nm fabrication process and have a front speed bus of 800Mhz similar to their predecessor. Both, the Intel E3200 and E3300 support virtualization which is very important if the owners of these processors decide to use Windows 7 and if they want to take advantage of the inbuilt virtualization technique provided by Windows 7.

Intel should have added support for virtualization to their low end processors long ago but better late than never. Intel also said that they will be marking the processors in such a manner that their compatibility with various motherboards can be easily identified.

Thermaltake Silent 1156

Intel Core i7 processors still have not become popular among the masses due to its high price but still Intel Core i7 processors provide a killer performance and have a great overclocking potential. But Intel Core i7 processors run extremely hot and their maximum temps. under load with the stock cooler can easily reach in excess of 80c. This is the reason why many manufacturers are coming out with cpu coolers for Core i7 processors. Today Thermaltake launched a new cooler for Socket 1156 based processors. This cooler comes with different type of fasteners compared to the ones you get with Socket 775 based processors so as to make the cooler compatible with Intel Core i7 and Core i5 (when launched) processors.

The Thermaltake Silent 1156 comes with a 92mm fan which has a RPM range of 800-1700 RPM. The fan is capable of moving 36 cubic feet/min of air and has a dBa of 22. The cooler has a dimension of 110*72*140 mm and the cooler weighs in only 382 gm. which is quite less compared to its Socket 775 cpu coolers. The design of the cooler is similar to other cpu coolers out there like OCZ Vendetta 2 and Thermalright Ultra eXtreme. How efficient this cooler is something only time will tell.

Kingston And OCZ Say Elpida Hyper Memory Chips Are Fine

Few days ago Corsair announced that its going to stop using Elpida hyper memory chips in their Corsair Dominator GT and XMS3 series of DDR3 RAM’s as these RAM chips are unstable under certain conditions. Corsair also recalled the RAM’s which used Elpida hyper memory chips and were already sold. Corsair said that many users were reporting instability issuse’s at various online forums and this forced Corsair to check the stability of RAM’s based on Elpida Hyper memory and Corsair actually found these RAM’s to be unstable under certain condition and thus Corsair started recalling RAM’s based on the Elpida Memory Chips.

Today though, Kingston and OCZ reported that none of its users were reporting any kind of issuse’s with RAM’s using the Elpida Hyper memory chips but Kingston and OCZ did say that if any of its users are facing any stability issuse’s then they can RMA the RAM.

Intel Core 2 Duo E7300 EOL

Intel E7300 which was released last year will soon be going out of production. Intel Core 2 Duo does not support virtualization which is very important now since Windows 7 has an inbuilt feature to virtualises incompatible application and to run them under Windows XP right from inside Windows 7. There is very little price difference between Intel Core 2 Duo E7300 and Core 2 Duo E7400. Currently its definitely worth it to spend the extra   bucks and get the E7400 as it supports virtualization.

Intel today said that from August it will only manufacture CPU’s which support Virtualization and will be stopping the production of all the CPU’s which don’t support Virtualization.

Corsair Recalls RAM Equipped With Elpida Memory Chips

Corsair today announced that it will stop selling DDR3 RAM’s equipped with Elpida Hyper’ memory chips as these chips tend to be unstable under certain conditions. Corsair also said that it will be recalling all the DDR3 RAM which were already sold to the end-user. The Elpida Memory Chips were usually used in high end Corsair Dominator GT and XMS3 DDR3 line up series. The affected products have the following part numbers – TW3X4G1600C6GTF, TR3X6G1866C7GTF, TR3X6G2000C8GTF, TR3X3G2000C7GTF and TR3X6G2000C7GTF.


The Elpida Hyper’ memory chips run at a speed of 1600Mhz, 1866Mhz and 2000Mhz at a rather low voltage of 1.2v-1.5v.

OCZ Launches Vertex Turbo SSD’s

OCZ had recently launched the Agility series of SSD’s and today OCZ have launched another new line-up of SSD the Vertex Turbo’. OCZ Vertex series of SSD’s have been quite a hit and no other SSD manufacturer has been able to match the popularity of the Vertex series of SSD’s from OCZ in terms of Sales. The OCZ Vertex Turbo SSD’s comes equipped with Barefoot memory controller manufactured by Indilinx, a Korean company, which offers a very good read/write performance at a very affordable price.

The OCZ Vertex Turbo comes in capacities of 30GB, 60GB, 120GB and 250GB. The Barefoot controller has been overclocked by OCZ and is now running at 180Mhz instead of the usual 166MHz found in the Vertex Series of SSD’s. Unlike the Vertex series, in the Vertex Turbo series of SSD’s the top of the line 250GB SSD gives the best read/write performance achieving speeds of upto 270MB/sec and 210MB/sec respectively. There has been no mention about pricing but looking at the 10-20% performance increase, the Vertex Turbo SSD’s will be available at a premium of 10-15% over the Vertex SSD’s. OCZ has also increased the warranty from 1 year to 3 years for its Vertex and Summit series of SSD’s including the SSD’s already sold to the customers. The increase in warranty of SSD only gives an example of how much OCZ trust their products which definitely is a good sign.

Virtualization Added To Lower Spec’ed Intel Processors

All the high-end processors of Intel came with Virtualization support but Intel never really equipped there lower end processors with virtualization whereas AMD on the other hand had added virtualization support to most of their processors in their line-up. Virtualization allows a user to run an operating system from within an operating system. Processors that supported Virtualization at hardware level provide better performance when/if a user runs an virtualized Operating system. Most of the users did not care for Virtualization since not many people require it and since the lower end Intel Chips were terrific overclocker, most of the people used to grab Intel’s lower end CPU’s, but all this is going to change with Windows 7.

Windows 7 supports virtualization natively and also has a feature to run *only* an application in emulation mode under a different operating system. This basically means all the people who brought the lower end Intel Processors are going to face performance issues’ when Windows 7 is officially released to the public. The shocking thing here was that even the low end quad cores from Intel did not support virtualization. Intel have finally realized there mistake and have now added Virtualization support to all their lower end processors. Here is a small image which compares the various processors from AMD and Intel on the basis of support of virtualization.

Macs Posts Higher Sales Growth Than PC

During World Wide Developer Conference 09′ this year, Apple announced new Mac Book and Mac Book Pro’s featuring unibody aluminium construction, 7hours of battery life and most importantly a lower price tag for the base model. The downside was non-user replaceable battery and a lower spec’ed hardware. All this has surely helped Apple as Macs have posted a higher sales growth compared to PC for the month of May. Apple posted a Sales growth of 25% month-to-month in May while the whole Computing market segment grew only 1% in May.

Apple is known to overcharge for all their products especially the Mac Book and Mac Book Pro’s. All the Apple products have been having a lot of issues recently including the iPhone 3G S and the Mac Book series of line-up.

Apple Says Sunlight Causes iPhone To Overheat

Apple recently at their World Wide Developer Conference 09′ launched a new iPhone the iPhone 3G S. The iPhone 3G S is no different from iPhone 3G from outside, its the inside which differ. The iPhone 3G S comes with a 600Mhz Processor and 256MB RAM which is double of what the iPhone 3G had. All these hardware changes made the latest version of iPhone very fast compared to its predecessor but with many Apple products recently, even the iPhone 3G S has been facing overheating Issues. Many people have been reporting that their iPhone 3G S becomes extremely hot when used heavily and some people who owned the white iPhone 3G S even said thatHT1871_1 their back white casing had turned pink/brown due to overheating. Soon after, most of the online forums were buzzing with the iPhone 3G S overheating issues.

Apple kept mum on this matter until today. Today Apple said that Sunlight is to be blamed for the iPhone 3G S getting overheated. Apple says that “”leaving it in direct sunlight for extended amounts of time” can lead to the iPhone overheating and not   functioning properly. Apple says -If the interior temperature of the device exceeds normal operating temperatures, you may experience the following as it attempts to regulate its temperature:
The device stops charging
Display dims
Weak cellular signal
Temperature warning screen appears with the message “iPhone needs to cool down before you can use it”.

You can read more of Apple’s disgusting excuse regarding the iPhone 3G S overheating here. All the products which Apple has been launching recently have been facing a lot of problems. First the SATA Speed being limited in newer Mac Book Pro’s, then the Display issues and now this. Its high time Apple changes the tagline It Just Works  which it uses in its advertising.

Nvidia ION 2 In The Making

Nvidia ION has literally revolutionised the netbook segment. The Nvidia ION chipset which is still available in limited quantity is able to play Full-HD Videos which the Intel Chipsets are unable to do. Currently the Nvidia ION platform contains the 9400M and the MCP79 Chipsets. Currently the Nvidia 9400M has 16 shaders which provide a respectable performance on a netbook. If rumours are to be believed, the ION 2 will contain twice the shader currently present in the ION platform i.e. 16 Shaders *2=32 Shaders. Nvidia themselves has made no announcement regarding ION 2 but sources say that the successor of ION that is ION 2 is due by the end of 2009.

Samsung Set To Launch Notebook Based On Nvidia ION Platform

Samsung is soon going to launch a notebook dubbed N510, based on Nvidia’s ION Platform. The Notebook will be equipped with an Intel N280 (1.6Ghz) Processor along with an integrated chipset based on 9400M. The notebook is rumoured to come with 11.6inch screen having a resolution of 1366*768. The notebook is also going to come with the usual 1Gb DDR2/DDR3 RAM, 160GB HDD, 3 in 1 Card Reader, 6 Celled Battery, Wi-Fi and finally Bluetooth. Nvidia’s ION platform has seen limited success among the Manufacturers. Samsung r620 -2

This notebook from Samsung is similar to various other Notebooks present in the market except for the 11.6inch screen and a higher resolution. The better graphic performance thanks to the 9400M Chipset is totally useless because I don’t think people use their notebook for gaming. According to me, its high time notebooks started coming equipped with a better processor. The Intel Atom N280 Processor kills the performance of most of the notebook especialy when multitasking. The Intel Atom N280 processor has been ruling the processor market of the notebook segment because of literally no competition. AMD still does not have an answer to Intel Atom based processor and thus it seems that Intel is in no mood to refine the architecture of Atom based processor for higher performance.

AMD Phenom II Black Edition TWKR CPU’s

phenom II TWKR black edition 00011

AMD is soon going to give-away Phenom II x4 Black Edition TWKR CPU’s to overclockers and will also be giving away few of these CPU’s in competitions. AMD Phenom II Black Edition TWKR CPU’s are hand picked from the production line and according to AMD they can overclock up to 7Ghz when the processor is cooled with Liquid Nitrogen. Only 100 of these CPU’s will be released though and none of them will be available in retail stores. The TWKR’ here stands for “Those Who Know”, and the R’ has been added to give it a tweaker’ kind sound when spelled.

These TWKR edition CPU’s have not been made with any special technology. It has been made in the same way other AMD Phenom II X4 CPU’s have been made, just that these CPU’s are more refined which basically means they can handle more voltage, higher clock speed etcetera. As the CPU’s manufacturing process grows older it can be refined so as to increase performance and reduce error.

AMD ‘Vision’

It has been reported that AMD is disappointed by the performance of its processors in the notebook segment. AMD is now looking for a change and is set to drop the Better By Designtagline from its processors and graphics card from September, with the launch of the Tigris Platform for Notebook based on 45nm Dual Core. AMD will instead reform its notebook line-up and call it as AMD Vision’. AMD Vision’ will divided into 3 categories, namely AMD vision trade mark

1) AMD Vision

2) AMD Vision Premium

3) AMD Vision Ultimate

Each category consists of an AMD Turion Processor and an AMD/ATi GPU coupled together for the Ultimate performance. Only the top end laptops will be branded as AMD Vision Ultimate which will consist of either the HD4650 and/or HD4870 while the average performing laptop will be branded as AMD Vision Premium and the low-end laptops will be branded as the AMD Vision. The AMD Vision Category will consist of AMD Neo x2 processor along with the Integrated HD3200 IGP.

Corsair HX750W And HX850W Are 80Plus Gold Certified Now

Recently Corsair had announced 2 new Modular PSU’s namely the HX750W and the HX850W. All the Corsair PSU’s are usually 80Plus Silver Certified but these 2 newly launched PSU’s are special because both these PSU’s are 80Plus Gold Certified instead of the usual 80Plus Silver Rating. The TX750W which is a non-modular PSU failed to meet this standard but itsCorsairLogo-Stacked-RGB modular sibling i.e. the HX750W met the requirements for being certified as an 80Plus Gold PSU easily. Techpowrup says To qualify for this rating, a PSU must provide an output efficiency of at least 87% at 20% load, 90% at 50% load, and 87% at 100% load. At these levels of load, the efficiency of HX750W was measured 88.04%, 90.02%, and 87.04% respectively, while those of the HX850W were 89.14%, 90.38%, and 87.06%

The Corsair HX750W and the HX850W are the first ever PSU’s made by Corsair to be certified as an 80Plus Gold SMPS. Corsair are known to make quality products and their SMPS/PSU’s line up are no different. How much they trust their products can be seen from the warranty which they provide on their products. The Corsair HX750W and the HX850W, both carry a warranty of 5 years. We should remember that even though these SMPS from Corsair are costly they are very good. We should never buy Cheap SMPS as it may lead to your PC not functioning properly and it may happen that the PSU may die under heavy load and may take along with it a few of your PC’s Components.
