It’s an advantage in terms of cost savings at volume, yes. But RAM prices are dropping quickly and it takes a lot of time to design those integrated SoCs, which limits the rate at which they can release new consoles.
Well cost is paramount on consoles, hence they do things like the unified memory and SoC’s. This last generation was the first time we saw a “mid generation” upgrade in hardware and that was 3-4 years after launch.

For folks interested in the software side of ray tracing, there is a free a apress ebook ray tracing gems. Free on kindle, and I imagine directly from a apress as an epub.
Also saw this ray tracing in Minecraft demo today:

AMD Navi leaks are starting. From WCCFTech so take with a load of salt, but it looks like AMD is abandoning HBM. Smart move, it’s a stinker and held them back.
Wccftech has been wrong in about 80% of the articles I’ve read from them. They know how to drive clicks but are usually full of shit.
Edit: “leak” articles specifically, I have no idea about the normal articles they may write about post-release benchmarks or whatever
I haven’t read the WccfTech article but FWIW if that’s about the PCB pic then they aren’t the actual source: a couple PCB pictures were posted on some Chinese forum by some random poster and soon deleted. Still a more reliable source than Wccftech.
The Beyond3d folks think it’s legit as in ‘not a fake picture’.

Never heard of this Youtuber until today but his analysis sounds plausible and pulls out way more info than I thought possible:
- GDDR6 memory
- 2x 8 pin power (that makes 250 - 300 watt possible)
- lots of VRM (voltage regulation)
- looks like a blower heat sink (yuck!)
- no sign if it’s an early engineering sample, late QA, or reference production board
- no indication if it’s a gamer card vs professional workstation card
- seems to have a USB 3 connector (not said in the vid but is in the comments… yes I sometimes read Youtube comments but at least I rarely browse WccfTech. I’ve got standards, man!)
- no real proof it’s Navi but what else could it be?
From AMD Computex keynote, Navi has a new architecture called RDNA that sounds like it will abandon compute, which will continue to be developed as a separate product line using GCN. They claim 1.25x per-clock performance and 1.5x performance per watt over Vega, which is a huge improvement.
BUT, and there had to be a but, they compared the Radeon 5700-series against… A RTX 2070. 10% faster. Womp, womp. AMD fails to compete at the high end, again.
I’m having trouble understanding the GPU implications of PCIe 4.0 (one of the marketing bullet points of the new Ryzen chips.) Are there any GPUs that can actually take advantage this feature if it’s just a faster version of 3.0 and not in a bottleneck? Apologies for any/all wrong assumptions in my question.
Nope, it’s meaningless marketing.
I mean, it allows motherboard makers to pack more ports into fewer PCI-e lanes, which reduces their costs. But for GPUs and anything less than high performance computing, the extra bandwidth is not useful.
Would that be the same price / wattage card? If so 10% is a lot.

AMD typically requires a lot more wattage to reach comparable performance, so I’m expecting this one to run really hot as well. Could be wrong, though.
Some price competition at that level would be great.
Nope. 2070 is basically a 1080; 2080 is a 1080ti.
Rumors are starting to come out about Nvidia’s “Super” 20-series refresh. This aligns performance closer to where it should have been on day 1. Pricing is rumored to stay the same, so you’re still paying that premium Nvidia tax.
The RTX2060S is basically as fast as a RTX2070/GTX1080, as it should have been to start off. The RTX2070S is basically a RTX2080/GTX1080ti as well. They’re both getting 256 additional cores and faster RAM.
The RTX2080S is getting a much smaller upgrade as it basically maxes out the TU104 GPU and it was already close. It only gets 128 cores and the faster RAM. This does make it a real upgrade over the 1080ti though, which it wasn’t before.
So far no info on the RTX2080ti going “super”. It is possible, as the RTX2080ti doesn’t max out the TU102, there’s 256 cores left unused there.
Unless Nvidia prices pretty aggressively I don’t see this having much impact on Navi.
I’m still humping along on my GTX1080. The only meaningful upgrade for me is a RTX2080ti and while I’m not particularly price sensitive, I’m not paying $1200 for a videocard either. Nvidia or AMD needs to come up with an upgrade path for me at <$600.

Sounds like we’re in the same boat, that’s where I’m at as well. I would like an upgrade to the 1080, but the RTX 2080ti doesn’t justify the ridiculous price tag.
If they can put out a 2070S at $500 I might upgrade from this 1070ti. It’s new enough I should be able to get some decent cash back from eBay.
I don’t need a huge performance boost but I’m way too close to 60 FPS as it is and I’m worried about the new releases over the next year.
If the super models can lock down ray-tracing performance, they should be good. For example the 2060 is a good card but slightly marginal at 1080p, and the 2070 is good but not quite great at 1440p raytracing if I recall correctly.
Rumored prices:
2060S = $399
2070S = $549
2080S = $699
Again, this is all rumor and may be completely wrong.
@stusser when you upgrade your GTX1080 , I upgrade mine!
