The Radeon RX 6000 series, AMD’s RDNA 2 desktop graphics card range, debuted at the end of 2020. The lineup brings AMD up to speed with NVIDIA’s RTX 30 series lineup, in some cases even quicker. AMD intends to revamp its RDNA 2 graphics card lineup with a new series of cards in 2022.
The new graphics card series, known as the RDNA 2 update ‘Radeon RX 6X50 XT,’ will use a comparable GPU design but will launch with new designs and better memory clock speeds.
So, to begin, the AMD Radeon RX 6000 ‘RDNA 2 Refresh’ lineup will be available in three versions. The Radeon RX 6950 XT, Radeon RX 6750 XT, and Radeon RX 6650 XT are among them. The AMD Radeon RX 6950 XT will be put above the Radeon RX 6900 XT, the Radeon RX 6750 XT above the Radeon RX 6700 XT, and the Radeon RX 6650 XT above the Radeon RX 6600 XT. Consider it AMD’s own ‘SUPER’ refresh, minus the main enhancements. The lineup is intended to deliver performance gains of 5% to 10%, with memory playing a key part in reaching these goals.
AMD Radeon RX 6950 XT – Navi 21 XTXH Powered Flagship
The Navi 21 XTXH GPU in its fully-enabled die config with 80 Compute Units or 5120 SPs will be included in the AMD Radeon RX 6950 XT. A 256-bit bus interface will connect 16 GB of GDDR6 memory to the board. On the graphics cards, there are also 80 Ray accelerators for ray-tracing support (one RA per Compute Unit). TBP for the graphics card will be around 300-350 Watts.
The Radeon RX 6900 XT graphics card will have 128 MB of Infinity Cache on the GPU die in addition to the normal memory. The cache will aid in increasing bandwidth for improved performance at resolutions higher than 1080p HD. The 128 MB Infinity Cache enhances the usual 512 GB/s bandwidth by 3.25x, giving all-Big Navi GPU-based cards an effective bandwidth of up to 1.664 TB/s.
AMD Radeon RX 6750 XT – The Fastest Navi 21 Mainstream
The Navi 22 XT GPU will be used in the AMD Radeon RX 6750 XT, which will have 40 compute units or 2560 stream processors. On the RDNA 2-based GPUs, the graphics processor additionally includes 40 Ray accelerators for raytracing.
The graphics card will include a 192-bit bus interface and a 12 GB GDDR6 memory buffer. AMD plans to use 18 Gbps dies, giving the cards a total bandwidth of 432 GB/s. There’s also 96 MB of Infinity Cache on the GPU. The GPU will be completely compliant with Gen 4.0. The TBP, on the other hand, is projected to have a 230-250W design. This is due exclusively to the usage of faster clock memory dies, which will result in higher power consumption. In terms of GPU clock speeds, we can’t say whether the RX 6750 XT will receive the same ‘boost’ treatment as the RX 6950 XT.
AMD Radeon RX 6650 XT – Navi 22 Powered Budget Delight
Finally, the AMD Radeon RX 6600 XT graphics card will be driven by the Navi 23 XT GPU, which packs 11.06 billion transistors into a 237mm2 die. The Navi 23 GPU has 32 compute units and 2048 stream processors in total. The card will also have a 32 MB Infinity Cache and an 8 GB GDDR6 memory capacity, with a total bandwidth of 288 GB/s and a 128-bit wide bus interface with pin speeds of 18 Gbps.
The card will use a single 8-pin connector, similar to the Radeon RX 6600 XT, and TBP is projected to be approximately 160-180W. Once again, we don’t know if the GPU’s boost clocks will remain the same as the present 6600 XT or will be increased. The graphics card will have a fresh new dual-fan ‘Midnight black’ reference design with dual slots and power delivered via a single 8-pin connector.
