AMD Zen 3 (5000 Series), rumored 17% IPC gain.

The thing that interests me most in that review is how the 1080ti is falling by the wayside in many of the tested games

 

[humbug]

LOL! Did Intel tell you that? I'll believe it when I see it, or else it's just another broken promise from Intel to go on their long list of broken promises.

He's trolling, ignore him

You noticed that too? The 5700XT is 20% faster than the 1080TI in Death Stranding.

But the reality is that Ryzen bottlenecks the fast graphics cards. Ampere quite a bit, next-gen even more so!
Ryzen 9 3900X will be bottleneck for Hopper and RDNA 3 | Navi 3 graphics cards.

 

[FoxEye]

He said to not expect IPC improvements of 30%.
If Intel doesn't deliver IPC improvements of those extents, how would Intel justify the lowered core count which should be offset by a relatively large IPC improvement.

Imagine 10-core 10th series i9 and 8-core 11th i9 series. Which will be better and why?

I must have missed part of the conversation.. why would they reduce core counts for Rocket Lake?

 

[LePhuronn]

Rocket Lake CPU's are going to slaughter AMD in games, unless Zen3 is an absolute beast!

That's not even a decent attempt at a troll. Do you want to try again?

 

[LePhuronn]

Power issues, apparently. There's talk that in backporting the design to 14nm has cause even bigger power delivery issues than Comet Lake to such an extent that it's not realistically possible to go past 8 cores on the LGA 1700 package. Rumours as always, so we'll see what happens.

Edit: there's even a suggested clock regression too. Intel's 5GHz "domination" may be over.

 

[LePhuronn]

as it should be around 30% more IPC over Cometlake (which is Skylake)

Oh, so Rocket Lake should draw IPC parity with Zen 3 then, given Zen 2 is around 15% higher IPC than Skylake and Zen 3 is pitched at 15-20% higher IPC than Zen 2.

exciting times ahead!

If you think inferior core counts, larger power draw, higher operating temps and a rumoured clock speed regression to be "exciting times" then I'll happily shout you a couple of quid for some new pants, because you're going to wet yourself!

Lol @ rocket lake....

Er nope..

 

[4K8KW10]

Intel's Ring bus gives very high inter-core bandwidth and very low latencies.
96 GB/s per core, means 960 GB/s in a 10-core Core i9-10900K. https://www.anandtech.com/show/3922/intels-sandy-bridge-architecture-exposed/4

AMD's Infinity Fabric https://en.wikichip.org/wiki/amd/infinity_fabric is much slower, and the result is much lower gaming performance. Because the games rely on heavy cross-talk between the individual cores.

What I don't get, is if Intel are such great gaming CPUs (as they seem outclassed in productivity areas) why are the new PlayStation and XBox based on AMD hardware? That's where the big gaming market for silicon lies.

Economy, politics and graphics IP. Radeon is much better.

 

[Bravetart]

I notice none of the obvious Intel fanboi postings ever post 4K results where they are basically identical. And I've not had an AMD CPU since Athlon XP

This is because a Bugatti Veyron with quad-turbocharged 60° V12 engine will be equally fast with a 2.0-litre ordinary diesel engine when on a road with 60 MPH speed limit :laugh:

Jesus, I didn't realize the 3080 had exacerbated the performance delta that much. Imagine what the 3090 tests will show!

It's going to be hard to resist upgrading to a Rocket lake CPU when they release, as it should be around 30% more IPC over Cometlake (which is Skylake), exciting times ahead!

"As an engineer, genuine clock-for-clock performance gains get me excited. Unfortunately Tiger Lake doesn't deliver much on this front, and in some cases, we see regressions due to the rearranged cache depending on the workload used. This metric ignores power - but power is the metric on which Tiger Lake wins.
Intel hasn't really been wanting to talk about the raw clock-for-clock performance, and perhaps understandably so (from a pure end-user product point of view at any rate)."

Because there’re not.

 

[humbug]

@Dave2150 IS Trolling, he's having a bit of fun, its what he does.

 

[Toasty]

Lol these trolls would have you believe you can’t game on a Ryzen system only 200fps compared to 230 at 1080p(lol)on a 3080 might as well chuck it in the bin.

In a blind test no way could they tell.

Only argument for Intel right now is if you enjoy overclocking

 

[alec]

Yea lets keep Intel talk and Intel trolls in Intel topics please

That's a good idea, @Dave2150 made his own thread for all this so there is no reason to keep it going in here.

Back to Zen 3....
