NVIDIA GT200 GPU and Architecture Analysis

Be the first to comment - What do you think?  Posted by JeGX - at 08:36

Categories: Graphics Cards   Tags: , , , ,

Beyond3D has published a very detailed article on the architecture of the GT200, the GPU behind the GeForce GTX 280.

Read tHe complete analysis HERE.

If it’s not clear from the above diagram, like G80, GT200 is a fully-unified, heavily-threaded, self load-balancing (full time, agnostic of API) shading architecture. It has decoupled and threaded data processing, allowing the hardware to fully realise the goal of hiding sampler latency by scheduling sampler threads independently of, and asynchronously with, shading threads.


NVIDIA GeForce GTX 280 Video Card

Categories: Graphics Cards   Tags: , ,

Benchmark Reviews has published a detailed review of NVIDIA’s new monster, the GeForce GTX 280.

The full review is accessible HERE.

In regards to performance and functionality, NVIDIA has redefined the graphics card space. Beginning with 240 processor cores, the GeForce GTX 280 is everything that previous products has not been: parallel-computing ready. Without question, the GeForce GTX 280 has earned the top position for NVIDIA’s video card product lineup. The core, shader, and memory clocks are at the launch-date reference level, so it might be a short while before drivers are stable enough to gain stable overclocks. Optimized post process compression combined with a future-proof 1024 MB of video frame buffer will make this the must-have card for extreme gamers for the foreseeable future.


NVIDIA GPU Compute FAQ

Be the first to comment - What do you think?  Posted by JeGX - at 08:22

Categories: Graphics Cards, NVIDIA CUDA, Programming   Tags: , ,

Benchmark Reviews proposes an article about GPU computing with CUDA and GeForce based graphics cards.

Read the complete GPU Compute FAQ HERE.

Terms such as “heterogeneous computing” and “parallel computing” are going to be used as often as the term “video card” is used in a product review. You won’t want to miss this evolution in graphics technology, because we are witness to a pivitol moment in time when computers are going to stop being filled with familiar single-purpose hardware. Benchmark Reviews offers this FAQ to help our readers understand what is happening, and help introduce them to what is coming. We don’t want anyone to be left in the cold when the rest of the world learns how the GPU is learning to be a CPU.

NVIDIA GeForce GTX 280 review

Be the first to comment - What do you think?  Posted by JeGX - at 17:33

Categories: Graphics Cards   Tags: , ,

The NDA is over. So all major hardware websites will publish in the next hours/days the reviews about the new NVIDIA flagship: the GeForce GTX 280.

Guru3D is one of the first to offer you such a review: NVIDIA GeForce GTX 280 review.

The GT200, the GPU with 1.4 billions transistors! Here are the main features:
* 993 GigaFLOP processing power
* 240 processing (shader) cores (GTX 280)
* 192 processing (shader) cores (GTX 260)
* DirectX 10 – OpenGL 2.1
* New power management enhancements
* CUDA parallel processing
* GeForce PhysX

The Verdict

We have to admit, the GeForce GTX 280 is simply put – a Greek power house. Spaaaartaaans!

Strangely enough there is another product out there that can actually compete with the GeForce GTX 280 rather well. It’s NVIDIA’s own GeForce 9800 GX2.

When we reverse things and look at the 9800 GX2, the GX2 however has 2x 128= 256 shader cores opposed to the 240 on the GTX 280 … that gives it a bit more bite and the GX2 shader domain is clocked a tad faster. So as this article has shown, the products both win and lose a little from each other.

Now then, if you’d ask me; the final word as far as I’m concerned is that the GTX 280 is the way to go here. Yes it’ll be more (too) expensive but with the GX2 you also have the problems that come with SLI, a lot of heat (2 GPUs) and a fair amount of power consumption. When games start using that excessive amount of frame buffer and complex shaders, the GTX 280 would seriously kick in.

Here is a small benchmark that try to compare several optimized Intel OpenCV library functions with their GPU analogs, written using OpenGL and GLSL shader language.

More information HERE.

Because I can’t resist, here is my score (Core 2 Duo 6600 default clocks, Radeon HD 3870 Catalyst8.5, WinXP 32-bit) with Resolution multiplier set to 4:

------------ CPU  | GPU
step1:       75.3   21.5
step2:       35.8   22.5
step3:       05.7   00.7
Total Time: 116.9  345.3

Here is a 1k intro by TBC. Keep in mind that a 1k intro is an executable with data and sound packed in only 1024 bytes!

This intro requires the latest DirectX redistributable and a fast graphics card supporting shader model 3.0.

Guru3D DriverSweeper

Be the first to comment - What do you think?  Posted by JeGX - at 08:45

Categories: Drivers, System Utilities   Tags:

Driver Sweeper is a fast tool to remove driver leftovers from your system (NVIDIA Forceware, ATI Catalyst, etc.). It’s very important to remove your drivers on a proper way, because driver leftovers can cause problems like stability and startup problems. You can use it if you want to update/remove drivers from your system.

Changes: improved NVIDIA File cleaning (CUDA), single click restore from system tray.

NVIDIA GeForce GTX 280 Preview

Categories: Graphics Cards   Tags: , ,

The chaps over at VR-Zone have managed to bench a NVIDIA GeForce GTX 280 1Gb.

Read the complete preview HERE.

Apparently preliminary testing did not show any jaw-dropping results. The NVIDIA GeForce GTX 280 can be considered as somewhat of a ‘re-work’ of the GeForce 9800 GX2 into a single core package with faster processing capability and more bandwidth.
