RADEON RX GAMMA XT

The latest leaks from a AIB vendors now have some new gossip for team red fanboys to drool over.

It is also something that immediately puts into perspective a lot of the leaks we have been seeing so far. AMD’s next-generation GPU will be known as Radeon RX Gamma XT.

Immediately the dual fan design is true to AMD’s promise to get rid of the despised blower design. Blower fans tend to howl once they get even a bit of dirt in them.

The block diagram shows that the Radeon RX Gamma XT will have 80 CU, This will give the card 5120 stream processors which is more than double the RX 480 in the rig right now.

The clock speeds are really eye opening. Based on the clock speed and assuming the same instructions as the last architecture, this card can deliver a resounding 26.6 TFLOPs of single-precision compute.

It also looks like AMD has doubled down on ray tracing with support for up to 21.2 Gigarays per second. By comparison, NVIDIA’s current generation RTX flagship the RTX 2080 Ti can only sustain a Gigaray count of 10. 

The card will be based on a DisplayPort 2.0, HDMI 2.1 and PCIe 5.0 and a board power of just 350W. A 512-bit bus will complement up to 32 GB of GDDR6 memory clocked at up to 24 Gbps. The card is built using AMD’s RDNA 2 architecture.

The graphic suggests GDDR7 but that is not standardized quite yet. JEDEC only has a draft version of the standard while discussions with manufacturers about design continue. The draft supports up to 32GB per device memory.
