GeForce 9500 GT 1GB GDDR3 vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 memory is set to run at a speed of 1100 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M375 should in theory be a lot superior to the GeForce 9500 GT 1GB GDDR3 in general. (explain)

Radeon R9 M375		35200 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 9600 (38%)

Texel Rate

The Radeon R9 M375 should be quite a bit (about 361%) more effective at anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 31800 (361%)

Pixel Rate

The Radeon R9 M375 should be a lot (more or less 269%) better at AA than the GeForce 9500 GT 1GB GDDR3, and also able to handle higher screen resolutions better. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that are processed in one second. This figure is calculated 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
