GeForce 9800 GTX+ vs Radeon R5 M330

Intro

Compare all that to the Radeon R5 M330, which comes with a GPU core clock speed of 1030 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 9800 GTX+ should theoretically be quite a bit superior to the Radeon R5 M330 overall. (explain)

GeForce 9800 GTX+		70400 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 56000 (389%)

Texel Rate

The GeForce 9800 GTX+ should be a lot (more or less 129%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 26632 (129%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 9800 GTX+ is the winner, and very much so. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 3568 (43%)

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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 get to the maximum fill rate.
