GeForce 9500 GT 1GB GDDR3 vs Radeon R5 M330

Intro

Compare those specs to the Radeon R5 M330, which makes use of a 28 nm design. AMD has set the core speed at 1030 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this particular model. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 9500 GT 1GB GDDR3 should in theory be quite a bit better than the Radeon R5 M330 overall. (explain)

GeForce 9500 GT 1GB GDDR3		25600 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 11200 (78%)

Texel Rate

The Radeon R5 M330 should be a lot (more or less 134%) faster with regards to texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon R5 M330		20600 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 11800 (134%)

Pixel Rate

The Radeon R5 M330 should be a lot (more or less 87%) better at AA than the GeForce 9500 GT 1GB GDDR3, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon R5 M330		8240 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 3840 (87%)

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 max amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
