AMD Radeon RX 6900 XTX Graphics Card Rumored To Function 18 Gbps GDDR6 Reminiscence, Elevated Clock Speeds With Navi 21 XTXH GPU, Sooner Than RTX 3090

AMD is allegedly engaged on its quickest Large Navi 21 GPU-based graphics card, the Radeon RX 6900 XTX. The brand new info comes from a slide that has been leaked by CyberPunkCat which states that the cardboard will function sooner reminiscence and clock speeds.

AMD Radeon RX 6900 XTX Allegedly In The Works, Might Function Navi 21 XTXH GPU With 18 Gbps Reminiscence & Sooner Clocks

The AMD Radeon RX 6900 XT presently has two variations, a normal variant that options the Navi 21 XT GPU and a binned variant that includes the Navi 21 XTXH GPU. Each of those variants are often called Radeon RX 6900 XT. Primarily based on the brand new rumor, AMD might be engaged on a 3rd variant that may mix the Navi 21 XTXH GPU with sooner reminiscence, permitting for sooner efficiency in gaming that may surpass NVIDIA’s GeForce RTX 3090.

In accordance with the alleged slide, the AMD Radeon RX 6900 XTX will function a compute horsepower of 24.93 TFLOPs. The prevailing reference Radeon RX 6900 XT contains a compute horsepower of 23.04 TFLOPs with a lift clock of 2250 MHz. With Navi 21 XTXH GPU on the Radeon RX 6900 XTX ought to function a lift clock of 2435 MHz. That is an 8% enchancment within the enhance clock for a 8% compute energy improve.

The second change comes within the type of reminiscence. The AMD Radeon RX 6900 XT is rumored to get 18 Gbps reminiscence dies which ought to ship a pleasant enhance in bandwidth over the prevailing 16 Gbps G6 chips. The cardboard will retain its 16 GB GDDR6 reminiscence capability however bandwidth needs to be boosted to 576 GB/s, a 12.5% enchancment over the reference card. All of those modifications will certainly have an effect on the GBP. The prevailing Navi 21 XT-based reference mannequin has a TBP of 300W so we might be round 350W TBP with the elevated clocks on GPU and reminiscence modules.

Additionally, you is perhaps questioning if such a card is sensible when AIBs have already launched Navi 21 XTXH variants. The AMD Radeon RX 6900 XTX would possibly find yourself being an OEM-only answer as AMD has already began providing an RX 6900 XT LC ‘Liquid Cooled’ variant to its PC & OEM companions. The slide apparently reads ‘Increasing The AMD RDNA Household’ which signifies that it might be a correct retail launch however that continues to be to be seen. As for efficiency, the AMD Radeon RX 6900 XT trades blows with the NVIDIA Geforce RTX 3090 graphics card so this variant would push that lead even additional.
