| EricHiggin said: 1550MHz seems too high, unless Navi has some voodoo magic or the PS5 is an XB1 at launch. XB1X is only 1175MHz, and that's with a vapor chamber heatsink. The memory does seem off. Either a 20GB pool, or 16GB with separate OS RAM like you said. I'm not worried about Zen 2 in terms of design or being ready, I'm worried about price. How much is a 6 core Ryzen 2 going to cost on 10nm or 7nm by late 2019, and hot much cheaper will PS get it for? While it should be semi custom and not a full blown Ryzen 2, I see the price potentially being an issue, unless they scale back elsewhere, up the launch price, or eat some more cost. If they had a long enough lead over Scarlet, they could just go with $499 for the first 6 months to a year, especially with the 25th anni hype. |
The GPU clock is possible since the AMD engineers behind the Zen CPU microarchitecture spent time on optimizing Vega's cache (that's where they blew most of the transistor budget on the new design) so that the whole GPU could achieve higher clocks and that's without using GlobalFoundries 12nm refresh node which is rumored for their upcoming new Polaris chip but that'll still probably clock lower compared to Vega ...
Navi will probably be built on 7nm but we don't have any idea if Sony is prototyping with it or if it's final shipping hardware since the original Orbis prototype featured 3rd generation Terascale chip equivalent to an AMD Radeon 6950 instead of a customized 2nd generation GCN chip like we saw shipping on base hardware ...
I'd assume that the architecture is still a moving target so that they can still bake in some more new hardware features though but the ballpark specs sounds fine for developing next gen games ...
