Plus benchmarks against Intel.
Like most people, I think 16 cores is completely no use to me, but do I want it? Absolutely!
The core count of the 3950X CPU is what I've been waiting for to replace my aging (and recently performance reduced) 4770k
Not that it matters much but i thought the I/O die was going to use 14nm, not the 12nm mentioned in the article, did AMD confirm 12nm for the I/O die?
Yes, Anandtech confirmed that it is indeed 12nm.
"Of course, Intel may well change its pricing stack in the wake of AMD's new threat"
Intel, Price cuts? Haha!! hell will freeze over before they'd stoop so low as to price cut because of anything AMD comes up with.
Their corporate culture will simply not allow it. They'd rather take the market share hit until they're ready next year with a response.
Whilst I don't think they will have a response as early as next year (10nm sucks for clock speeds so they are stuck with enhanced 14nm until their 7nm comes out) I agree they probably won't budge on price. After all, people kept buying the Pentium 4 and that was a piece of junk whereas what Intel are selling now is OK silicon, just might not be as good as AMDs in some circumstances. So corporate types will keep buying Intel chips in huge quantity.Quote:

Am i the only one who thinks the 3800X seems rather poor value from a gaming perspective?
I agree with you in every regard, if you are gaming on the high end the GPU matters more than the CPU thanks the higher workload on that end. No point in putting money into something that won't be utilized properly. the r5 series is most likely to dominate again. I think I might wait to see if they bring out a 4 core 8 thread again (w// no igpu) but idk?Quote:

Edit: I gather Zen2 has some countermeasures to the speculative execution problems, will be nice to see some stuff like retpoline turned off.
The picture I take from that is that gaming is often not bottlenecked by CPU, though interestingly minor differences across architecture remain at different price points, even though the chip might be slower or faster in the range.
Aye, I've noticed my 4690K has been playing up recently to the point where I've applied my end of life extending overclock (I buy an overclockable chip with mobo and cooling and then overclock when it begins to bottleneck. This is usually when a new game comes out but I think it's due to the security patches this time as the games haven't changed but the performance has dropped substantially).Quote:

Also, likely shorter longevity due to the running temps and the higher demands on PSU and power delivery system. I had a desktop P4 in a laptop. Cooked itself.
More than likely, I've seen a 'noticeable' decrease with these security patches and as such have been looking to bring forward my update for my 4790k.... on some sites it's saying the combined performance loss is around 16% on newer generation cpu's which according to intel aren't as badly affected as our generation.Quote:

A few have commented on this, but I'll add to it. Reducing pricing has a direct effect on gross margins, which is a measure of the profit margins per dollar of sales. Intel's share price has always been propped up by its monopolistic or near monopolistic status which allowed it to maintain very high historical margins.
The stock market looks very closely at that gross margin metric. The moment there is a price war, the share price will tank sharply due to the gross margin deterioration. Therefore Intel will be loathe to engage in a straight price war, especially on its latest products (9th & 10th gen crap).
At the same time, if they do not cut price, market share will take a hit. However, this metric is less of a headline metric in the quarterly earnings announcements. Less of a knee jerk reaction to share prices.
However, in Germany and some other countries already, reports are showing AMD outselling Intel by more than 2 to 1. Despite the unit sales disparity, so far the sales dollars taken in is about the same for both due to the higher Intel prices.
But given that AMD's lead in price-performance ratio is continuing to widen, that will change very soon. When total volume and total sales revenue drops, Intel will be caught with its panties down and the shares will eventually tank one way or another too.
Truth be told, Intel is in a world of hurt whichever path of least hurt it chooses. The recent trend showing declines in Intel share prices (and conversely the rocketing AMD share price) says it all and is poised to continue with greater velocity until Intel gets its act together on 10nm and 7nm. That seems to be a few years away still!
I was thinking of going for a Ryzen 7 originally, but now I'm starting to consider a Ryzen 5. Will definitely need to await for proper benchmarks to come first.
Just to add to this, it seems (Ian Cutress tweet) we're both right:Quote:

So for clarity: Rome large IO die = GF 14nm Matisse small IO die = GF 12nm X570 Chipset = Matisse IO die on GF 14nm That's right. The X570 chipset is the same floorplan as the Matisse IO die, but with diff chicken bits enabled/disabled. AMD has good reuse of chips
If that's true... well I wasn't expecting that :DQuote:
