A 1700 with 1 CCX disabled as a 4+0 is going to be better in 99%+ of games than any 2+2 or even 3+3.
That really ticks me off. I don't want to spend more than I need to for twice the cores over a 1400 or 1500X just to have to disable cores and restart my computer to get the most out of some games and the performance that the Ryzen 4 cores SHOULD have.
You're talking an average 20% difference between 2+2 and 4+0 in games, when 4+0 is already going to be 10-20% behind the 7700k.
No, I didn't expect a 50% better CPU for half the price, but I'd have hoped for a 4c/8t that's 50-65% the cost of a 7700k and 80-90% the performance. Which is what a 1700 with 1 CCX disabled would have been.
Yes AMD needs to "maximize yields" so what are they doing to CPUs with 3 cores defective on one side, but all 4 cores fine on the other?
They needed to release a 4+0 part in the R5 series to truly compete.
The 1600X and 1500X both don't compete. They'll both be slower in many games than a 6 year old i5-2500 or the 2c/4t i3-7350K because of the CCX issue that virtually no game accounts for.
Hell I'd have been happy to pay $200+ for a 4c/8t that's actually 4 cores on one CCX without that CCX issue. I don't want to wait/hope that the issue is fixed in Windows scheduler and game patches for years old games.
Even at 3.5/3.9ghz and its lower IPC, it still probably would have been faster than the i5-7600k in most games thanks to SMT. But no, we get 2+2s that'll be worse than an Intel 2 core in gaming.
I'd bet thousands of dollars that the average performance for the 1500X is going to be worse than the i3-7350K across any decent average selection of games that reviewers commonly use, if there was any legit betting pool going on. That's how bad this is.
It's not just bad, it's sad. So sad and stupid that AMD didn't prioritize salvaging 4+0 cores and just sold the 2+2 to OEMs or something.
I'm guessing that the number of naturally defective chips where SMT doesn't work on either CCX is so low that those are just being tossed because there aren't enough chips to have a product category and there's no point in artificially gimping functional parts that can be sold at a higher cost, where they're probably guaranteed to sell as Intel hasn't cut prices yet. The R5 chips are going to stack up quite well against the i5 chips given they're capable of three times as many threads.
... or they're being sold as cheaper R3s later this year?
