Discussion Intel current and future Lakes & Rapids thread

[Hitman928]

Correction: They appear to be inefficient in the range where the 12900k can start to beat the 5950x in some MT workloads.

How a 12700k compares vs a 5900x, or a 12600k compares vs a 5800x is still very much TBD. And as somebody with a limited budget, I am far more interested in the latter two comparisons.

12700k and 12600k do look like the sweet spot for ADL to me as they should be able to compete/win in most tasks without haven't to draw crazy high power to do so. Intel still doesn't really have an answer to AMD's chiplet/Zen 3 approach when it comes to high core counts (relative to each segment), but ADL at least gets them back in the game for consumers.

 

[IntelUser2000]

I wouldn't be surprised if Zen 3 is more efficient, but I also wouldn't be surprised if it uses more power under 5.3GHz, since it's likely beyond it's design target frequency. Gracemont might end up less efficient in the 4GHz range. Does that mean Golden Cove is a more efficient chip? NO!

We can see from mobile Tigerlake that it becomes relatively more efficient at higher frequencies compared to Cezanne. That still means little as it ends up being less efficient overall anyways. It just fares better.

Zen 3 performs like Alderlake without needing the hybrid configuration and without needing to be in 2021. I'm pretty sure at some point in the future Intel chips will become competitive with current generation AMD parts in all areas but that's not what Alderlake is.

Golden Cove is still merely an expansion of Sandy Bridge and thus continue to follow the sublinear scaling of performance in regards to performance and die area. Nothing noticeably new.

People already have CPUs in their hands and testing in variuos games:

1% and 0.1% would make first gen Ryzen look like a champ. FPS jank is visible on graph, even if averages look awesome

GOOD: Run on 3600 DR DDR4, while not "peak", i doubt memory latency is causing the jank.
BAD: Scheduler?

So overall at least on DDR4 things are fine, disable the E cores in BIOS, lock the clocks and have the best gaming machine?

 

[Gideon]

Surprisingly good average results though yeah 1% is beyond terrible. If this is an omen of what's to come V-cache vs Alder lake will become very interesting (I'm pretty sure V-cache will help with 0.1% and 1% more than with average)

I've always been curious about this. At what point would it make consumers value minimums more than average fps? Would people willingly take a 20% hit on average fps if it mean their minimums were 20% better? What if it were 50% better? Of course, this assumes that the average is already well above playable frame rate to begin with. If not, then yes I could see the argument of chasing higher averages.

Absolutely amazing performance from the 12900HK. Probably @ 65W though.

Take those numbers with a grain of salt. pre-release drivers, bios, etc.

I think AMD should have no problem handling Alder Lake with a +15% in games increase using v-cache 3dnow!

Could easily be way more than that.

It's strange though. Look at AssCreed. I know the guy made multiple videos to maximize views but this is what he got:

12900K - ~ 86 fps
10900K - ~ 80 fps
12700K - ~ 74 fps
5800X - ~ 71 fps
5600X - ~ 70 fps

You would think the 12700K shouldn't be much slower than the 12900K. Also Comet Lake is beating Zen 3.

With a 3070, perhaps that increase would be greater with a 3090.

Could easily be way more than that.

It's possible that it could be done at 65W, virtually all of the multi-core Geekbench tests use less power than Cinebench. On an 11800H, it can run 400-600 MHz higher on Geekbench than CB R23 for the same power use.

What I mean is there's Tiger Lake-H laptops out there with PL1 of way higher than 65 W, at least from notebookcheck's reviews. It could be 80, it could easily be triple digits.

I think that's related to benchmark setup and early compatibility issues. All tests are using almost 100% of GPU so any extra average framerate gain comes from CPU performance. Maybe Golden coves are going idle for power saving much more than Ryzen does so it makes frame-time suffer sometimes, resulting in a worse 1% and 0.1% FPS

These benchmarks are looking good for Intel. Good that AMD is giving Intel great competition. Fierce competition is good for us end users. Imagine in 2 years with this type of competition.... faster cpus and lower prices, we win!

Can't wait for anandtech's reviews on Alder Lake.

 

[jpiniero]

and lower prices, we win!

Doesn't work that way, esp with the inflation going on. Appears that the official MSRP of Alder is going to be quite a bit more per brand (although probably not as high as speculated).

What laptop out there has an 80W PL1 TGL-H???

I think you are confusing PL2, which is not a sustained boost.

Guess that answers my questions about the boards.

Comparing i9-11900k/i7-11700k pricing to i9-12900k/i7-12700k pricing makes little sense given that the latter are in clearly different performance levels to the former. If the recent MC leaks hold water $670 for 12900k and $470 for 12700k look pretty competitive as far as pricing is concerned.

Good. It outperforms the M1 Pro and Max. Actually Apple chose to compare it to 11800H, since it would make it look much more impressive.

I do think Geekbench 5 will end up underestimating the impact of the hybrid configuration, as the test is so short that it doesn't stress the Golden Cove cores much and pretty much runs close to peak, while as in real world applications it won't happen.

I saw a number of posts today that I didn't have time to reply to, but I will reply to yours, because, why not?!?

A good Geekbench 5 benchmark is as good as a SPEC benchmark. Prove me wrong. Even certain folks at AT claim this. The reason GB5 is called out as being "inaccurate" is that 100% of the population of the world has access to it (and can run it in garbage scenarios), vs. 5% of the population that happens to be able to pay up for a SPEC license (who run SPEC in a controlled environment like their very livelihood depends on it...I would too).

I'm not defending Intel, of course (though I'm sure the usual suspects will claim otherwise), but one thing we do know is that, based on these benchmarks, and absent data regarding power, Intel beats Apple and AMD hands down when it comes to CPU performance. Period.

SPEC has quite a few benchmarks surrounding power. I expect that the general power benchmarks will favor AMD/Apple, and the performance benchmarks will see Intel leading, though I refrain from making assumptions, regardless. We will see.

 

[IntelUser2000]

A good Geekbench 5 benchmark is as good as a SPEC benchmark.

Each of the subtests take less than a minute to run, so while it might be a decent bursty scenario test such as web browsing, in the hybrid scenario where the efficiency cores are supposed to boost MT, it won't show it's full potential.

Case in point is how well Amberlake-Y does in Geekbench ST, while it does poorly everywhere else. You know how people are saying the phone chips are close to 28W chips based on GB ST test?

Well, according to Geekbench, Intel's own 4.5W Amberlake-Y is only about 10% slower than the top of the line U chip. So you can go get yourself an Amberlake-Y laptop and it'll be almost as responsive as the 28W U laptop right?

NO.

In reality, the U chips are more than 50% faster than Amberlake-Y in single thread. That's because even in single threaded scenarios, the core goes well past the 4.5W mark. Actually we can see they need well over 10W.

That should tell you how "good" of a benchmark Geekbench is. It can't even load a single core properly! Can't justify comparing that to SPEC.

 

[arandomguy]

Surprisingly good average results though yeah 1% is beyond terrible. If this is an omen of what's to come V-cache vs Alder lake will become very interesting (I'm pretty sure V-cache will help with 0.1% and 1% more than with average)

I'd be very skeptical about the 1% and 0.1% low numbers from those videos at the moment.

Comparing known examples of the 11900k and 10900k the numbers are horrendous compared to the numbers we've seen elsewhere. Even the channels own video with the 10700k a few weeks ago (same RTX 3070) has 1% lows in HZD at in the 70s and RDR2 in the 50s, yet the 10900k numbers are below 20 for HZD and in the 30s for RDR2 in this recent comparison.

The numbers in general seem to suggest that both the 11900k and 10900k would be extremely noticeable stutterfests across some of the games tested, yet we do not have wide reports or other tests that show that to be case.

Also in some tests the numbers are 0 for both 1% and 0.1% lows.

I'd be wondering if there is some testing methodology issue going on here. 1% and even more so 0.1% low are much more sensitive to testing issues than avg fps numbers, which makes them harder to work with. Just glancing at the channel it seems to going for a very quantity approach to content.

Apple chose to compare the M1pro/max to the 11800H because laptops with Alder Lake aren't released. Changing from a i7 TGL-H to i9 TGL-H SKU realistically should have minimal impact on the perf/watt metrics being compared anyways.

12900HK score looks very, very impressive. Even accounting for the liberties Intel are taking with power consumption, it would most likely take 12 Zen 3 cores to match the results from 6GC + 8GM here in a similar power envelope.

With Alder Lake, it will takes more cores in aggregate to match performance with AMD in an efficient manner, which is fine for Intel as some of those cores are tiny. 12900k looks bad efficiency wise because they pushed clocks up hard to try matching 8GC + 8GM cores with 16 Zen 3, when in reality 8P + 8E takes the area of 10P and should be a better match for the 5900x. It'd be an interesting exercise to see how ADL's performance scales with power consumption.
