*** AMD "Zen 4" thread (inc AM5/APU discussion) ***

Looks to me that 7600X is an incredible gaming CPU. :eek:
It should be with what its going to cost !
AMD release has timed badly for the UK plus the cost of the available motherboards.
As yet, there is no Price/performance cpu available.
Hope they roll the b motherboards out quickly. Will make the 7600x far better value for people.

(For reference OC's sold the 12600ks for £248 on launch and they now cost £260 - £330)
Intel got screwed with DDR5 and AMD got screwed (for UK) by the pound and overall higher costs.
 
Right now the £ buys $1.07

So $299 would be £279.4 + 20% VAT = £335.2

£325.99, £10 cheaper than it should be right now.


Like I said we had our stock land before it went totally low, but once its gone and if we have to re-buy at 1.07 the price will go up. For how we can pass the savings on. :)
 
7900x and Vengeance 32GB for me, currently hovering over the buy button, the problem is the motherboard.

Really wanted the MSI MEG Ace, but its come in at the predicted eye watering £850..... Anyone else considering it?
Really want the built-in 10gb NIC and 4 m.2 slots (without the next for expansion card).
Went with the Asus ROG Hero in the end, couldn't justify the extra £200, I'll save that for the graphics card.

Now I need to go lie down.....

No, i've had my 5800X for two years and its regular used under high load with not 95c as i have tuned it but above 80c, health wise the silicon is exactly the same today as it was the day i installed it.

I think whats going on here is the upper limit of the CPU is higher than that 95c, probably 115c and AMD have set it to 95c so it doesn't burn out the silicon.

It seems to me these days everything runs hotter, your cited Ampere Memory IC's, Intel CPU's can run at over 100c and it doesn't bother them, especially in laptops where they run at high temperatures if you breath on it, i do think we need to get over our anxiety of these sort of temperatures, its not a problem.
I could swear I saw in one of the reviews the max limit is 115C not 95C, so I think you are right. It's not like the CPU throttles massively when it reaches 95C either (it's not an R9 290X with the reference cooler) and AMD stand by their warranty.

If the CPU has been designed to run at 95C all day every day then it is just a number at the end of the day, I remember people thinking 70C with Zen 2 was dangerous too. Power draw is often significantly lower than Intel so it won't heat up your room as much even if it is running at 95C.

I'm pretty sure the blender power draw from hwunboxed showed a 7600X now pulls more power than a 12600k so not significantly lower. Its also not as efficient in this workload as a 12600k or 5800X either.

A mate of mine lent me his reference 290X when i was stuck for a GPU, at the time 6 years old it was still going strong apparently cooking away at 95c, #### it was loud tho... no joke those coolers are horrible for noise. It did sound like a hairdryer, that sort of volume, nearly.
He's still got it, its still running now at 9 years old, its in one of his kids PC's.

I do wonder if too many people equate PC component temperature to the rise in room temperature, those that do need to go back to school.

Hmmm interesting. It does seem rather different at the top-end though. Gamer's Nexus had a very interesting section on efficiency in their 7950x review


It does feel as if AMD pushed Zen4 a little bit higher in terms of power use than they may have intended in order to eek out a more significant performance gain over last gen. It is a backward step from the stunning efficiency of Zen3, but then Intel has gone all out for performance despite power use recently, and sounds as if they'll be going even further with Raptor Lake.
 
If you work with blender and need a new system, the 7950x seems like a no brainer:


Smashes it in these tests
 
Well, i'm glad i chose a 12700K as my upgrade path at the end of last year. Got it for an amazing price compared to what they are going for now, and the 7700X is not only not as fast, it is decently more expensive than what i paid for my 12700KF last year and would force a DDR5 buy that i didn't need.

Pretty poor show from AMD this time around.
