Compare any two graphics cards:
Radeon HD 4670 1GB vs Radeon HD 4670 512MB
IntroThe Radeon HD 4670 1GB features a clock speed of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory speed of 1100 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.Compare all of that to the Radeon HD 4670 512MB, which uses a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory works at a speed of 1000 MHz on this card. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthAs far as performance goes, the Radeon HD 4670 1GB should in theory be just a bit better than the Radeon HD 4670 512MB in general. (explain)
Texel RateBoth cards have the exact same texel fill rate, so in theory they should be equally good at at AF. (explain)Pixel RateBoth cards have the exact same pixel rate, so in theory they should be equally good at at full screen anti-aliasing, and be capable of handling the same resolutions. (explain)
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

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once 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 AA, HDR and higher screen 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 number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

One Response to “Radeon HD 4670 1GB vs Radeon HD 4670 512MB”with out doubt the wiiu gpu is based around the hd4670 level of gpu give or take
everything at vgleaks points to the 4670 or 5670 AMD gpu cores likely 4670 shrunk and optimized with 32mb edram embedded into the gpu logic
