AMD "Navi" Features 8 Streaming Engines, Possible ROP Count Doubling?

AMD's 7 nm "Navi 10" silicon may finally address two architectural shortcomings of its performance-segment GPUs, memory bandwidth, and render-backends (deficiency thereof). The GPU almost certainly features a 256-bit GDDR6 memory interface, bringing about a 50-75 percent increase in memory bandwidth over "Polaris 30." According to a sketch of the GPU's SIMD schematic put out by KOMACHI Ensaka, Navi's main number crunching machinery is spread across eight shader engines, each with five compute units (CUs).

Five CUs spread across eight shader engines, assuming each CU continues to pack 64 stream processors, works out to 2,560 stream processors on the silicon. This arrangement is in stark contrast to the "Hawaii" silicon from 2013, which crammed 10 CUs per shader engine across four shader engines to achieve the same 2,560 SP count on the Radeon R9 290. The "Fiji" silicon that followed "Hawaii" stuck to the 4-shader engine arrangement. Interestingly, both these chips featured four render-backends per shader engine, working out to 64 ROPs. AMD's decision to go with 8 shader engines raises hopes for the company doubling ROP counts over "Polaris," to 64, by packing two render backends per shader engine. AMD unveils Navi in its May 27 Computex keynote, followed by a possible early-July launch.

AMD Radeon RX 3080 XT "Navi" to Challenge RTX 2070 at $330

Rumors of AMD's next-generation performance-segment graphics card are gaining traction following a leak of what is possibly its PCB. Tweaktown put out a boatload of information of the so-called Radeon RX 3080 XT graphics card bound for an 2019 E3 launch, shortly after a Computex unveiling. Based on the 7 nm "Navi 10" GPU, the RX 3080 XT will feature 56 compute units based on the faster "Navi" architecture (3,584 stream processors), and 8 GB of GDDR6 memory across a 256-bit wide memory bus.

The source puts out two very sensational claims: one, that the RX 3080 XT performs competitively with NVIDIA's $499 GeForce RTX 2070; and two, that AMD could start a price-war against NVIDIA by aggressively pricing the card around the $330 mark, or about two-thirds the price of the RTX 2070. Even if either if not both hold true, AMD will fire up the performance-segment once again, forcing NVIDIA to revisit the RTX 2070 and RTX 2060.
