Radeon HD 4670 1GB vs Radeon R9 M375

Intro

The Radeon HD 4670 1GB comes with a GPU core clock speed of 750 MHz, and the 1024 MB of GDDR4/GDDR3/DDR3/DDR2 memory runs at 1100 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 32 TAUs, and 8 ROPs.

Compare those specs to the Radeon R9 M375, which uses a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 memory is set to run at a frequency of 1100 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon R9 M375 will be a lot (approximately 69%) better at AF than the Radeon HD 4670 1GB. (explain)

Radeon R9 M375 40600 Mtexels/sec
Radeon HD 4670 1GB 24000 Mtexels/sec
Difference: 16600 (69%)

Pixel Rate

The Radeon R9 M375 will be a lot (more or less 171%) better at full screen anti-aliasing than the Radeon HD 4670 1GB, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M375 16240 Mpixels/sec
Radeon HD 4670 1GB 6000 Mpixels/sec
Difference: 10240 (171%)

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 max amount of information (measured in MB per second) that can be moved 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, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends 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 max fill rate.
