GeForce GT 220 GDDR3 vs Radeon R7 M265

Intro

The GeForce GT 220 GDDR3 makes use of a 40 nm design. nVidia has set the core frequency at 625 MHz. The GDDR3 RAM runs at a speed of 1012 MHz on this particular model. It features 48 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare that to the Radeon R7 M265, which features clock speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 220 GDDR3 should in theory perform a bit faster than the Radeon R7 M265 overall. (explain)

GeForce GT 220 GDDR3 32384 MB/sec
Radeon R7 M265 32000 MB/sec
Difference: 384 (1%)

Texel Rate

The Radeon R7 M265 will be much (approximately 74%) faster with regards to anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R7 M265 17400 Mtexels/sec
GeForce GT 220 GDDR3 10000 Mtexels/sec
Difference: 7400 (74%)

Pixel Rate

The Radeon R7 M265 will be just a bit (about 16%) faster with regards to anti-aliasing than the GeForce GT 220 GDDR3, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon R7 M265 5800 Mpixels/sec
GeForce GT 220 GDDR3 5000 Mpixels/sec
Difference: 800 (16%)

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 maximum amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
