GeForce GTS 250 1GB vs Radeon R9 M265X

Intro

The GeForce GTS 250 1GB makes use of a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 RAM runs at a frequency of 1100 MHz on this specific model. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Compare all of that to the Radeon R9 M265X, which uses a 28 nm design. AMD has clocked the core frequency at 575 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

GeForce GTS 250 1GB 70400 MB/sec
Difference: 1600 (2%)

Texel Rate

The GeForce GTS 250 1GB will be much (approximately 105%) better at texture filtering than the Radeon R9 M265X. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 24232 (105%)

Pixel Rate

The GeForce GTS 250 1GB will be much (about 28%) better at anti-aliasing than the Radeon R9 M265X, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTS 250 1GB 11808 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 2608 (28%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
