GeForce 9500 GT 512MB GDDR3 vs Radeon R9 M265X

Intro

Compare those specifications to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has clocked the core frequency at 575 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this 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 M265X should in theory be quite a bit better than the GeForce 9500 GT 512MB GDDR3 overall. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon R9 M265X will be quite a bit (approximately 161%) faster with regards to texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 14200 (161%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M265X is superior to the GeForce 9500 GT 512MB GDDR3, by a large margin. (explain)

Radeon R9 M265X		9200 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 4800 (109%)

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 max amount of information (in units of MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant 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.
