Compare any two graphics cards:
Radeon HD 4670 1GB vs Radeon HD 4670 512MB
IntroThe Radeon HD 4670 1GB has a GPU clock speed of 750 MHz, and the 1024 MB of GDDR4/GDDR3/DDR3/DDR2 memory is set to run at 1100 MHz through a 128-bit bus. It also is made up of 320(64x5) SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 4670 512MB, which features core clock speeds of 750 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR4/GDDR3/DDR3/DDR2 memory. It features 320(64x5) SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.
Display Graphs
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 superior to the Radeon HD 4670 512MB in general. (explain)
Texel RateBoth cards have the exact same texel rate, so theoretically they should perform equally good at at AF. (explain)Pixel RateBoth cards have exactly the same pixel fill rate, so theoretically they should perform equally good at at full screen 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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max 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
