Intel’s surprise Ryzen killer
- Thread starter Wulfster
- Start date
The 2 key metrics for me are single thread performance and power efficiency (as that also relates to heat). Cores are nice but not critical.
Even AMD in their last presentation have now admitted single threaded performance is important, now they have finally caught up on that, they are open about it.
If Intel e.g. did a 30% IPC boost with no power increase or even a power drop, they of course would be in led again on the desktop even if its capped to 8 cores. Remember not everyone is an encoder. Most people are generic desktop users or gamers.
The consoles are 8/16 cpu's so for most situations 8/16 will be the point where after extra cores give you diminishing returns in games. Unless you are multitasking at same time such as streaming and gaming on one PC.
Any cpu's with more than 8 cores to me are halo products, so I wait and see what intel can do, we need good competition, if they go back in the lead, then these new ryzen chips will go down in price, think on that.

Don't forget Zen 4
- Supports PCI-e Gen 4.0 Protocol
- AVX512 can achieve greater performance (But it runs really hot even under 8 cores and leads to higher power consumption)
- Both L1 cache & L2 cache sizes have increased. 10th generation core is L1 32KB / L2 256KB while 11th generation core is L1 48KB / L2 512KB.
- Summary: Although the 11th generation Core is 14nm, there is a real change in performance.
- Architecture has improved gaming performance. It is a lot stronger than the 10th generation Core, but it is still a long way from AMD in Cinebench R20 and R15 (Multi-threading) because core count is still only 8 cores while AMD has up to 16 cores.
- It is very easy to run overclock all cores to 5 GHz.
- Drop-in compatibility with Z490 motherboards with PCIe 4.0 support on boards that have the necessary hardware integration. Z490 VRMs are sufficient to overclock the 11th generation.

I will tell you - don't hurry with the purchases - let's wait and see what will happen in March-April next year.

Does AMD have an equivalent bounty program to pay researchers to find their security flaws?
I think AMD has security issues as well - as I recall the search for these focussed mostly on intel as they pay you to find them.
AMD has missed it's taste of bad press on this issue - much like bumblebees and wasps... they both sting but everyone hates on wasps despite being important in pest control for crops...
Also it's not dissimilar to Trump's desire to not test for COVID - more testing on intel shows more security flaws. At least we know about them!

Yeah I think I meant that intel pay for someone to find the intel flaws. Not sure if AMD do the same.
Intel only pay a bounty after any work has been done and once that bounty is paid, Intel can then insist the bounty receiver does not then publish any findings.
Most of Intel's important security flaws have actually been found by research institutions that have never asked for payment from Intel, or indeed received payment. As a side note, those research institutions have found that AMD cpu's do not have the same security flaws.
I think that most of us on here are fully aware that Intel ignored the security flaws so that their cpu's would seem to be faster. The fact that full mitigation of those security flaws actually cripple Intel cpu's performance is proof of that.
AMD don't need to pay anyone outside of AMD to find those flaws for 3 reasons. First, they run proper security design,second they are not hoodwinking the customer and third, the same research institutions that have caught Intel with their pants down would have caught AMD as well.
It is very easy to run overclock all cores to 5 GHz. < That almost certainly isnt true, if it was, then the cpus would all have it as turbo clock.
Intel are going down the wrong path, AVX512 should be dead, performance at the cost of more power and heat shouldnt be a consideration in 2020.
AMD is going the wrong route, too, no 45 or 54 watt CPUs, only one 65-watt 6-core and everything else up is 105-watt.

Are you referring to Threadripper and other power hungry HEDT chips?
Yeah I think anything marketed at consumers should have power usage at the heart of it, we were going in that direction when core2duo got launched and then again with sandy bridge, but now we going on a race for pure performance with power usage going up and up and up. I guess the price of a core arms race.
Same with gpu's things were going in the right direction, then last 2 gens going in the wrong direction again.
Yeah I wish they had more low end stuff. Need a sub 50 watt cpu.
They've got loads of 35w parts, I've been using them a while now, not in the same volume as the T series Intel parts but a good few. What are you looking for?
They have them.
They exist, they're just not the flagship products.

Theres always something flashier round the corner, or at least there has been for a shed load of time. Even my soon to arrive 3080 will look old-hat and decidedly short of vram in the blink of an eye.
Which 3000 or 5000 series slot chips you suggest then? One's using zen2 or 3 tech, I am aware of the zen+ variants.
