Radeon HD 5770 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 frequency at 1030 MHz. The DDR3 RAM is set to run at a speed of 900 MHz on this specific card. It features 320 SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5770 should be 433% faster than the Radeon R5 M330 overall, due to its greater data rate. (explain)

Radeon HD 5770		76800 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 62400 (433%)

Texel Rate

The Radeon HD 5770 will be a lot (more or less 65%) better at anisotropic filtering than the Radeon R5 M330. (explain)

Radeon HD 5770		34000 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 13400 (65%)

Pixel Rate

The Radeon HD 5770 will be much (about 65%) faster with regards to anti-aliasing than the Radeon R5 M330, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 5770		13600 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 5360 (65%)

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 (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
