GeForce GTX 970M vs Radeon HD 5550

Intro

The GeForce GTX 970M uses a 28 nm design. nVidia has clocked the core frequency at 924 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this model. It features 1280 SPUs as well as 80 Texture Address Units and 48 ROPs.

Compare all of that to the Radeon HD 5550, which has core clock speeds of 550 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 320(64x5) SPUs as well as 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 970M is 650% faster than the Radeon HD 5550 in general, due to its higher data rate. (explain)

GeForce GTX 970M 96000 MB/sec
Radeon HD 5550 12800 MB/sec
Difference: 83200 (650%)

Texel Rate

The GeForce GTX 970M is much (approximately 740%) faster with regards to anisotropic filtering than the Radeon HD 5550. (explain)

GeForce GTX 970M 73920 Mtexels/sec
Radeon HD 5550 8800 Mtexels/sec
Difference: 65120 (740%)

Pixel Rate

The GeForce GTX 970M should be a lot (about 908%) better at FSAA than the Radeon HD 5550, and also able to handle higher resolutions better. (explain)

GeForce GTX 970M 44352 Mpixels/sec
Radeon HD 5550 4400 Mpixels/sec
Difference: 39952 (908%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
