GeForce GTS 150 vs Radeon R9 M375

Intro

The GeForce GTS 150 has a clock speed of 740 MHz and a GDDR3 memory speed of 500 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare those specs to the Radeon R9 M375, which has a clock frequency of 1015 MHz and a DDR3 memory frequency of 1100 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375 should in theory be a small bit better than the GeForce GTS 150 overall. (explain)

Radeon R9 M375 35200 MB/sec
GeForce GTS 150 32000 MB/sec
Difference: 3200 (10%)

Texel Rate

The GeForce GTS 150 should be a little bit (approximately 17%) better at anisotropic filtering than the Radeon R9 M375. (explain)

GeForce GTS 150 47360 Mtexels/sec
Radeon R9 M375 40600 Mtexels/sec
Difference: 6760 (17%)

Pixel Rate

The Radeon R9 M375 will be a lot (more or less 37%) faster with regards to FSAA than the GeForce GTS 150, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 M375 16240 Mpixels/sec
GeForce GTS 150 11840 Mpixels/sec
Difference: 4400 (37%)

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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its 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 card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
