 2019-07-09, 11:59 #1 M344587487     "Composite as Heck" Oct 2017 3×5×53 Posts Navi (RX 5700, RX 5700XT) They've flown under the radar thanks to zen2 but they're out. They are fundamentally different enough to Vega and Polaris that the performance for TF/LL/PRP/P-1 cannot accurately be predicted, it'll need testing. Basic specs: RDNA architecture, a new arch focused on gaming performance over compute performance. This probably makes the cards perform more similarly to nvidia's lineup than anything else (aka good TF performance and poor LL/PRP/P-1 performance relative to a Radeon VII, testing required) 36 CU's for 5700, 40 for 5700XT 8GB GDDR6 448GB/s bandwidth 7nm, comparable energy consumption to nvidia's lineup 1:16 DP (I think) There's a lot of gaming benchmarks out there which peg the 5700 at around 2060S levels, the 5700XT at 2070S levels FWIW, with slightly better power consumption. Probably won't get one as much as I want to test it, can't justify buying another toy. If you're considering one I'd wait about a month unless you don't mind early adopter teething issues (especially for Linux). Only reference blower cards exist ATM which are loud as hell, AIB's are expected mid-August which are probably worth the wait.

The memory bandwidth is also quite lackluster with the gddr6, so I am not expecting much from these cards, maybe getting around the same performance as a stock vega 56 would after overclock.

I'm hoping that by going the gaming focused route that they gain the same strength nvidia did when they did the same, TF performance. LL/PRP/P-1 I'm expecting very little from these cards. Do you think good TF is wishful thinking?

Gotta see someone running AIDA64 GPGPU test on Navi, and hopefully the INT32 performance is equally to the FP32 performance (same as RTX) because as of current implementation only INT24 is identical to FP32 perf and not FP32. I seriously doubt it will be the case, I think it will TF worse than Vega series.

For example, it was rumored more than a year ago that Navi would be the first GPU from AMD to feature circuitry dedicated to artificial intelligence (AI) operations.

I agree. I ordered one RX 5700 XT and waiting for arrival to test it. That should cut on useless words.

Waiting for the tests
