GeForce GTX Titan vs Radeon R5 M330

Intro

Compare those specifications to the Radeon R5 M330, which features core clock speeds of 1030 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan should theoretically be quite a bit faster than the Radeon R5 M330 in general. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 273984 (1903%)

Texel Rate

The GeForce GTX Titan is quite a bit (approximately 810%) better at AF than the Radeon R5 M330. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 166888 (810%)

Pixel Rate

The GeForce GTX Titan will be a lot (more or less 388%) more effective at anti-aliasing than the Radeon R5 M330, and also able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 31936 (388%)

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 largest amount of data (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
