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

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthPerformance-wise, the Radeon HD 4670 1GB should in theory be a small bit superior to the Radeon HD 4670 512MB in general. (explain)
Texel RateBoth cards have the exact same texel fill rate, so theoretically they should be equally good at at anisotropic filtering. (explain)Pixel RateBoth cards have the exact same pixel fill rate, so theoretically they should perform equally good at at anti-aliasing, and be able to handle the same screen 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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video 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 amount of Raster Operations Pipelines by the the card's 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach 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
