GeForce 9500 GT DDR2 vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The DDR3 RAM runs at a speed of 1100 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 should be 120% quicker than the GeForce 9500 GT DDR2 overall, because of its greater data rate. (explain)

Radeon R9 M375		35200 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 19200 (120%)

Texel Rate

The Radeon R9 M375 should be much (about 361%) more effective at AF than the GeForce 9500 GT DDR2. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 31800 (361%)

Pixel Rate

The Radeon R9 M375 is much (about 269%) faster with regards to full screen anti-aliasing than the GeForce 9500 GT DDR2, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 11840 (269%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
