RDNA 3 was designed to support high clock speeds. On RDNA 3, clock speeds have been decoupled with the front end operating at a 2.5 GHz frequency while the shaders operate at 2.3 GHz. The shaders operating at a lower clock speed gives up to 25% power savings according to AMD and RDNA 3's shader clock speed is still 15% faster than RDNA 2. [19]

RDNA 2 is a GPU microarchitecture designed by AMD, released with the Radeon RX 6000 series on November 18, 2020. Alongside powering the RX 6000 series, RDNA 2 is also featured in the SoCs designed by AMD for the PlayStation 5 , Xbox Series X/S , and Steam Deck consoles.
Graphics DDR SDRAM (GDDR SDRAM) is a type of synchronous dynamic random-access memory (SDRAM) specifically designed for applications requiring high bandwidth, [1] e.g. graphics processing units (GPUs).
Each EU has a 128-bit wide FPU that natively executes eight 16-bit or four 32-bit operations per clock cycle. [20] Double peak performance per clock cycle compared to previous generation due to fused multiply-add instruction. [20] The entire GPU shares a sampler and an ROP. [20]
At Hot Chips 2016, Samsung announced GDDR6 as the successor of GDDR5X. [5] [6] Samsung later announced that the first products would be 16 Gbit/s, 1.35 V chips.[7] [8] In January 2018, Samsung began mass production of 16 Gb (2 GB) GDDR6 chips, fabricated on a 10 nm class process and with a data rate of up to 18 Gbit/s per pin.
This is called texture mapping and is accomplished by texture mapping units (TMUs) on the videocard. Texture fill rate is a measure of the speed with which a particular card can perform texture mapping. Though pixel shader processing is becoming more important, this number still holds some weight. Best example of this is the X1600 XT.
The extra layer can be decompressed by the CPU so that the GPU receives a normal compressed texture, [3] or in newer methods, decompressed by the GPU itself. Supercompression saves the same amount of VRAM as regular texture compression, but saves more disk space and download size. [4
