Vega 64 performance for $250 would be amazing.
Yes but tbf prices are the least accurate things to leak because they change so much & so readily. Heck, even if it turns out to be £300-350 a lower TDP V64 would be fantastic. Essentially a cheaper and better RTX 2060 but without the RTX non-sense, and with enough vram for a gpu in 2019.
Although those leaked prices always felt optimistic, I'm starting the think that the source for these either didn't know about Radeon 7, or the prices were determined before AMD knew how underwhelming and expensive RTX would be. Follow me here
The latest AdoredTV video alludes to some rushing around inside AMD regarding Radeon 7 in that a couple of consumer Vega 20 SKUs were planned, but cancelled because it wasn't going to be viable. But then when RTX came out and was overpriced nonsense, the opportunity to get back into the game presented itself by repurposing Instinct packages. Whether or not AMD are using stuff that would've ended up in the trash because it didn't make the cut for Instinct, or they're actually digging into MI50 stock is largely irrelevant, but with those packages AMD can trade blows with the RTX 2080. And lo, the Radeon 7 becomes a thing and priced at $699.
So let's say this thought process is legit. It's entirely possible that AMD said to themselves "we're not fighting the top end, so let's be disruptive at the midrange with aggressive pricing" and pitched their Navi 10 RX 3080 at $250 for RX Vega 64 +15% performance. OK, cool, that would be a fantastic card. But now, Radeon 7 is RX Vega 64 +25% performance for $699. There is no way in hell the 10% increase from RX 3080 to Radeon 7 is worth an additional $449. It's too big a jump.
As a related digression, the Navi leaks show 2 products based on a Navi 12 and only 1 based on Navi 10. It's logical to say that the RX 3070 is fully-fledged Navi 12 with the RX 3060 based on a cutdown version. By extension then, it's logical to say that RX 3080 is based on a cut-down Navi 10, thereby leaving a full-fat version waiting in the wings; if the cut-down Navi 10 is RX Vega +15% performance, would the full version be RX Vega 64 +25%? +30%?
So either Radeon 7 is a short-lived product to be replaced by that fully-working Navi 10 at $449, or the 3 Navi cards as leaked get $150 added to their price point to better align them with the Radeon 7's performance and equivalent RTX prices.
Unfortunately the latter is the most likely.
