AMD announced three new Graphics Card on Wednesday( 28/10/2020).
Radeon 6900 XT , 6800 XT, RX6800 These Graphics Card are direct competition to Nvidia Graphics Processor which was currently available( RTX3090 , RTX 3080)
These processor was built using TSMC 7nm node and it has 26.8 billion transistors .
These processor are built using new RDNA 2 Architecture these leads to 65% increase in power per watt ratio when compare to previous Generation Architecture.
Feature of this new Graphics processors:
Cache : AMD named their cache as AMD Infinity Cache . They have implemented 128MB cache with 256bit 16Gbps bandwidth this will increase the performance for GPU and reduce the latency while gaming.
AMD Standard Access memory: This feature will help the CPU can access the GPU memory directly. While this feature only possible if you going to connect AMD GPU with AMD CPU.
These processor also support the Direct x 12 and Direct X ray tracing . Ray tracing is possible by Hardware Ray Accelerator special compute unit implemented inside the chip.
AMD GPU Processor information:
6900 XT :
Compute units – 80 , Game Clock – 2015MHz, Boost Clock – Up to 2250 MHz
6800 XT:
Compute units – 72 , Game Clock – 2015MHz, Boost Clock – Up to 2250 MHz
RX6800
Compute units – 60 , Game Clock – 1815MHz, Boost Clock – Up to 2105 MHz
All these three GPU has same,
Memory – 16 GB, Memory Interface – 256 bit , Infinity Cache – 128MB
