GeForce 9800 GTX+ vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which features 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 comprised of 320 Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9800 GTX+, in theory, should perform quite a bit faster than the Radeon R5 M330 in general. (explain)

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

Texel Rate

The GeForce 9800 GTX+ is quite a bit (more or less 129%) more effective at AF than the Radeon R5 M330. (explain)

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

Pixel Rate

The GeForce 9800 GTX+ is a lot (approximately 43%) better at FSAA than the Radeon R5 M330, and able to handle higher screen resolutions while still performing well. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
