GeForce 8300 GS (OEM) vs Radeon HD 6990

Intro

The GeForce 8300 GS (OEM) comes with clock speeds of 450 MHz on the GPU, and 400 MHz on the 128 MB of DDR2 memory. It features 8 SPUs as well as 4 TAUs and 2 ROPs.

Compare all of that to the Radeon HD 6990, which makes use of a 40 nm design. AMD has clocked the core speed at 830 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this model. It features 1536 SPUs along with 96 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM) 40 Watts
Radeon HD 6990 375 Watts
Difference: 335 Watts (838%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6990 is 4900% faster than the GeForce 8300 GS (OEM) overall, because of its greater bandwidth. (explain)

Radeon HD 6990 320000 MB/sec
GeForce 8300 GS (OEM) 6400 MB/sec
Difference: 313600 (4900%)

Texel Rate

The Radeon HD 6990 will be much (approximately 8753%) more effective at AF than the GeForce 8300 GS (OEM). (explain)

Radeon HD 6990 159360 Mtexels/sec
GeForce 8300 GS (OEM) 1800 Mtexels/sec
Difference: 157560 (8753%)

Pixel Rate

The Radeon HD 6990 should be much (approximately 5802%) more effective at FSAA than the GeForce 8300 GS (OEM), and capable of handling higher resolutions while still performing well. (explain)

Radeon HD 6990 53120 Mpixels/sec
GeForce 8300 GS (OEM) 900 Mpixels/sec
Difference: 52220 (5802%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
