Seems like low latency 3000 MHz memory would be the best bet, both from peak performance and the variety of choice available. I am curious what the raw bandwidth coffee lake gets from each set speed.
We now know however that ram clocks determine infinity fabric speeds, and as such, interthread communication benefits massively from higher speed ram on Ryzen, something not really covered in that review.
Clearly it doesnt make that much difference. If it did, the multi core encoding benchmarks would have shown massive boosts from higher speed memory. Same with the compression and rendering benches. The performance improvements were in line with what coffee lake gains, suggesting that infinity fabric was not a bottleneck there.
I'm pretty sure AMD would have pushed the multiplier up if there was that much performance left on the floor.
How about 5Ghz gaming tests /w the uncore maxed out on a GTX 1080Ti? I doubt the stock 4.3Ghz core & 3.7ghz uncore speed is enough to max out the memory @ 3600mhz+
Based on? Games have not been memory bandwidth limited for a very, very long time. DDR4 finally pushed the last holdouts, games like supreme commander, to their limits, and it is highly unlikely going from 4.3 to 5 GHz would significantly increase memory bandwidth demand to make the jump from 3000 to 3600Mhz memory noticeable. Going from 2666 to 3000 already shows practically no performance gain.
Game engines are simply not built to handle that much power. to benefit, you would need a game engine built to use that much bandwidth effectively, and such an engine would not work on consoles. Outside of perhaps cloud imperium, I cant imagine anybody modding a PC engine that much.
