Final Ryzen IPC estimates - where do you think it will land??

[CAT-THE-FIFTH]

Now that AMD has finally got down to releasing Ryzen next week - will it be a Ryzen sun or a fallen star??

What are your final IPC estimates for the CPU especially for gaming??

I think around Haswell level or might be a bit higher for gaming.

Where do you think it will land?

 

[AiiR]

Between Haswell and Skylake, leaning closer to Haswell.

The 6900K is boosting to 4Ghz in single threaded.
The 1800X to 4.1Ghz.
The 7700K to 4.5Ghz.

The 1800X is clocked 2.5% higher than Broadwell but scores 6.5% higher in single threaded, so that is a 4.5% IPC advantage to Ryzen over Broadwell (Haswell)
The 7700K is clocked 9% higher than Ryzen and scores 18% higher, so a 9% IPC advantage to the 7700K

So Ryzen compared to the last couple gen Intel chips.

RyZen vs Broadwell / Haswell / Devils Canyon = 104.5% to Ryzen.
RyZen vs SkyLake / KabyLake = 109% to SkyLake / KabyLake.

Edit: +7% to RyZen vs Broadwell / Haswell / Devils Canyon in games?

The benchmark 163 is 4Ghz 1800X without the XFR, from the AMD video. (on crap motherboard and RAM while aircooled).

@OP

The Ryzen IPC is better than Broadwel which is better than Haswell, less so against the Skylake and Kabylake (which are same IPC).

The i7 7700K works at 4.5Ghz with score 193.
If we extrapolate by applying the same 4.5Ghz to the 1800X the single core score it will be 183

Skylake 6700K at 4.2Ghz on an Asus Z170 Deluxe has single core score 183 also.
If we extrapolate by applying the same 4.2Ghz to the 1800X the single core score it will be 171

BUT. The multithread perf is way better than the Intel SMT. Hence it beats on multithread the 6900K at same spead by a hefty margin.

So take back the 2.5% higher clock of Ryzen and give it back to IPC, it would = 7%, exactly the same the Sniper slide.

RyZen vs Broadwell / Haswell / Devils Canyon = 107% to Ryzen.
RyZen vs SkyLake / KabyLake = 107% to SkyLake / KabyLake.

Bang in the middle of the two.

Same as skylake or a couple of % less.

That initial batch of benchmarks from videocardz had a 1700X about 22% behind (a 7700k) for clock speed on a board they suspected wasn't letting it boost when the 7700K was scoring about 22% more in single thread (there was no boost detected, certainly).

The Ryzen was on a crap board with average ram though so... imo anything up to equal IPC is still _possible_

Napkin math here being:

Ryzen          7700k
 \/             \/
3.4ghz   vs   4.4ghz              =  22.2% slower or 77.27%
 2046    vs    2625        for single thread score = 77.94%

So... if you brought the Ryzen up to 4.4ghz, you're looking at VERY similar scores so... we're at VERY similar IPC.

Surely Intel wouldn't be dropping the prices if Ryzen was not just as fast or at least pretty dam close. Its already more expensive than a 7700k.

Within 5% of KabyLake

It doesn't compete with a 7700k but some people are thinking it does. AMD did not demo anything vs the 7700k except that (obviously) the 7700k loses in multithreading vs a core monster with double the threads. But you wouldn't be using a 7700k for hugely threaded workloads.

The AMD 8 cores are aimed at making intels 6, 8 and 10 core processors look bad which it's safe to say they do. I don't think core for core on same clocks its a big deal but the cost difference is comical and very clear.

I'm referring (above) to https://videocardz.com/65825/first-amd-ryzen-7-1700x-benchmarks-are-here
so... maybe a pinch or more of salt required? I dunno.
