nVidia GT300's Fermi architecture unveiled
An interesting tidbit of info just surfaced on the web through Bright Side of News, regarding NVIDIA's upcoming GT300 chip (high-end graphics card part. I'll do the blunt copy/paste here:
nVidia GT300 chip is a computational beast like you have never seen before. In fact, we would go as far out and state that this is as closest as GPU can be to a CPU in the whole history of graphics technology. Now, time will tell whatever GT300 was the much needed revolution.
Beside the regular NV70 and GT300 codenames [codename for the GPU], nVidia's insiders called the GPU architecture - Fermi. Enrico Fermi was an Italian physicist who is credited with the invention of nuclear reactor. That brings us to one of codenames we heard for one of the GT300 board itself - "reactor".
When it comes to boards themselves, you can expect to see configurations with 1.5, 3.0 GB and 6GB of GDDR5 memory, but more on that a little bit later.
This is the meat part you always want to read fist. So, here it how it goes:
- 3.0 billion transistors
- 40nm TSMC
- 384-bit memory interface
- 512 shader cores [renamed into CUDA Cores]
- 32 CUDA cores per Shader Cluster
- 1MB L1 cache memory [divided into 16KB Cache - Shared Memory]
- 768KB L2 unified cache memory
- Up to 6GB GDDR5 memory
- Half Speed IEEE 754 Double Precision
As you can read for yourself, the GT300 packs three billion transistors of silicon real estate, packing 16 Streaming Multiprocessor [new name for former Shader Cluster] in a single chip. Each of these sixteen multiprocessors packs 32 cores and this part is very important - we already disclosed future plans in terms to this cluster in terms of future applications. What makes a single unit important is the fact that it can execute an integer or a floating point instruction per clock per thread.
TSMC was in charge of manufacturing the three billion transistor mammoth, but it didn't stop there. Just like the G80 chip, nVidia GT300 packs six 64-bit memory controllers for a grand total of 384-bit, bringing back the odd memory capacity numbers. The memory controller is a GDDR5 native controller, which means it can take advantage of built-in ECC features inside the GDDR5 SDRAM memory and more importantly, GT300 can drive GDDR5 memory in the same manner as AMD can with its really good Radeon HD 5800 series. The additional two memory interfaces will have to wait until 28nm or 22nm full node shrinks, if we get to them with an essentially unchanged architecture. You can expect that the lower-end variants of GT300 architecture will pack less dense memory controller for more cost efficiency, especially on the memory side.
Ferni architecture natively supports C [CUDA], C++, DirectCompute, DirectX 11, Fortran, OpenCL, OpenGL 3.1 and OpenGL 3.2. Now, you've read that correctly - Ferni comes with a support for native execution of C++. For the first time in history, a GPU can run C++ code with no major issues or performance penalties and when you add Fortran or C to that, it is easy to see that GPGPU-wise, nVidia did a huge job [via bsn].

ASUS to offer sub 99 USD P55 motherboard
ASUS is preparing a new P55 motherboard that will address the 'budget' market. It is the P7P55 LX. Supporting socket LGA 1156 processors, the P7P55 LX is intended to be priced even lower than the P7P55D LE (under 100 EUR).
It's all a little basic like the 5 phase CPU power circuit. You do however gain the latest ASUS extra's like MemOK, ExpressGate, and TurboV.
You will spot one PCI-Express 2.0 x16 (looks like two .. but the second one only is a x4 (!). Good enough for say PhysX or something else. Then two PCI-E x1, and three PCI. All six SATA 3 Gbps ports are assigned as internal ports. An additional controller provides an IDE connector. Integrated is also 8-channel audio with optical SPDIF output, and gigabit Ethernet make for the rest of the feature-set.
Paired with a Core i5 750 at 199 USD this might be a very sweet deal.

Tomorrow the 30th of September 2009 ...
Just a quick heads up on info on the fact that we are finalizing a review on the Radeon HD 5850 (CrossfireX as well). Please check back in tomorrow (Wednesday) for a full review.
NVIDIA and Microsoft collaborating on GPU computing
NVIDIA today announced work with Microsoft to promote NVIDIA Tesla graphics processing units (GPUs) for high performance parallel computing using the Windows HPC Server 2008 operating system.
Volume limit on MP3 players in the EU
The European Commission has decided to set volume limits for MP3 players in all European Union member states, which means your Zune HD won't be able to output anything louder than 80 decibels under the default settings when the ruling goes into effect. According to Consumer Affairs Commissioner Meglena Kuneva, "It's easy to push up the sound levels on your MP3 player to damagingly loud levels, especially on busy streets or public transport.
And the evidence is that particularly young people -- who are listening to music at high volumes sometimes for hours each week -- have no idea they can be putting their hearing at risk. It can take years for the hearing damage to show, and then it is simply too late."
Microsoft -- no Windows 7 restrictions on netbooks
Microsoft announced that they have removed the netbook restrictions that previously prevented OEM and ODM from installing any version of Windows 7 on their netbook. The lifted restriction means OEM and ODM can install Windows 7 starter on a netbook, and that the three application restriction has been removed as per consumer's request.
"OEMs and ODMs have the choice to install any version of Windows on a netbook," a Microsoft UK spokesperson said. "[But] Starter is an entry version and doesn't have many of the consumer or business features. The three application limit isn't there anymore."
Windows 7 Starter and Home Basic variety only come in 32bit versions and are missing a variation of features from the higher end versions. Some of the features missing from Windows 7 Starter include:
- Aero Glass
- Taskbar Preview
- Aero Peek
- Desktop personalization
- Fast user switching
- Multi-monitor support
- DVD playback
- Support for domains and XP Mode
- Windows Media Center
Home Basic also lacks some key Windows 7 features including Aero, Taskbar Preview, Internet Connection Sharing and some other features. Windows 7 Home Basic will not be sold in the US, Europe and other established markets, while Windows 7 Starter will be available through OEM.
Retail stores and manufactures will be able to strip some of the cost off their netbooks using Windows 7 Starter or Home Basic. Microsoft will now have two entry level SKU versions of Windows 7 in some markets [via neowin].
ATI Eyefinity review
With the release of Radeon series 5800 comes a new feature. It's called Eyefinity. Eyefinity in short is having the ability to connect multiple monitors to your graphics card and create an extreme native resolution. It allows you to setup two to six monitors, combine them and make one massive screen.
Guru3D will put this to the test today as we combine three 24 inch Dell monitors and try out a good number of games. The idea is to create a much more immersive state of gameplay. Especially for flight simulators , racing games and strategy games where you like to have a big field / area to play in it enhances visibility, this feature could just be really grand.
Wanna have a look ? We are going to show you some video's of ATI Eyefinity as well. Check out Guru3D's article right here.
Tuniq Propeller 120 CPU cooler
More CPU cooling news today as Tuniq has released its Tuniq Propeller 120, an elegant CPU cooler inspired by the design of aircraft carriers.
The heatsink features four 8mm direct-touch heatpipes, aluminum fins and a 120mm MFDB (Magnetic Fluid Dynamic Bearing) fan with a max airflow of 90.65CFM and a noise level of 16-20dBA. Included with the kit is a tube of TX-3 thermal grease and also a fan controller to adjust the speed of the fan between 1000RPM and 2000RPM.
The Tuniq Propeller 120 CPU cooler took its visual inspiration from the mighty aircraft carriers. The four specially designed smooth-curving heatpipes are both aesthetically pleasing and highly functional.
The 120mm MFDB fan blows downward and is one of the best performing fans on the market; and when matched with the four specially designed heatpipes, the Propeller 120 is able to achieve the same top level performance of competing designs with eight heatpipes. We have also included the top performing TX-3 thermal compound and a fan controller to maximize performance and flexibility.
Intel Gulftown comes with tower HSF
I guess even intel now ahs to admit that six CPU cores can make quite a lot of heat, especially for the consumer part. At IDF Intel showed the processor cooler for its upcoming six-core Gulftown processors.
As you can see this is a tower heatsink with four heatpipes, a large PWM fan, and a bolt-thru mounting kit instead of flimsy push-pins. It's unknown if Intel will ship this with all Gulftown processors, or only with the Extreme Edition models. Different from the previous design, the fresh cooler employs tower design with horizontal blowing for enhanced airflow, and it features four copper heatpipes.
Als, no irritating Push-pin any more. It installs with screws.
Nvidia disables PhysX when ATI card is present
Well for all those who have used Nvidia cards for PhysX and ATI cards to render graphics in Windows 7, that is about to change.
Since the release of 186 graphics drivers Nvidia has decided to disable PhysX anytime a non-Nvidia GPU is even present in the same PC. We do feel that Nvidia has shot themselves in the foot here.
In NVIDIA's defense, they have been saying ever since the beginning that they would not support the ATI / NVIDIA combo PhysX wise, it is now a little more definitive though.
Small advise to NVIDIA, PhysX will be a lost cause unless you guys get ATI onboard as well. This certainly isn't helping.
Thermaltake Contac 29 Multi-Socket Budget CPU Cooler
Thermaltake, leading DIY thermal solutions brand, launches a multi-socket support budget CPU cooler, the Contac 29. The Thermaltake Contac29 offers excellent cooling performance and a formidable price point when compared with the current competition on the market. Its Direct Contact Technology allows the three 8 mm heatpipes to immediately touch the CPU and thereby maximize the cooling effect. The multi-socket support offers excellent compatibility and flexibility in the choice and upgrade of your processor. It supports all major Intel sockets such as the LGA1156, LGA1366 and older LGA775 models. As for AMD, sockets AM3, AM2+ and AM2 are supported.
The three u-shaped heatpipes transfer processor heat up into the aluminum heatsink fins. In a second step the preinstalled 120 mm PWM fan blows air over the layered fins to further increase cooling efficiency, while the specially curved fins prevent outside heat to intrude the dissipation area.
As the Contac 29 is equipped with full PWM functionality the fan speed control is taken care of by the motherboard which automatically adjusts the speed according to actual CPU load between 800 and 2000 RPM. Even at highest speeds potential noise development is kept at the lowest level by using Anti-vibration Soft Mounts that virtually eliminate movement of the fan.
If you want to further maximize cooling efficiency, Thermaltake has already included a second set of Anti-vibration Soft Mounts which you can use to install another 120 mm exhaust fan across the preinstalled in-take fan.
EK Water Blocks for Radeon HD 5870
The SKU name will be EK FCS5870 and it will keep the primary heat sources chilled down, including GPU, memory, and VRM. The first picture below shows a CAD drawing the design. The second one is a picture of the finalized copper block. FCS5870 is expected to be available in ten days or next weeks.
