With the new architecture the 12100 should had no problem destroying the 11400 in gaming, instead the 11400 scored wins. This is not what everyone was expecting out of the 12100 due to the high IPC the new architecture was promising.
The 11400 scored wins because it's no slouch, with it being a 6C/12T CPU. And the selection of games is such that except for perhaps CS:GO, all of the other games show some scaling with core count.

I don't see why you think a 4 core, 4.3 GHz turbo chip with 60W power should destroy a 6 core, 4.4 GHz chip with 65W power (that also costs $60 more).

i3 12100, don't listen to what the mean gentleman in saying, you're a perfect little CPU and anyone would be lucky to have you. No, your cache isn't small, it's just... well proportioned.

Now move away from that 3090 and go play with some webpages. Yes, you can open Office too. We'll talk later on Skype.

Gigabyte at least mentions dual channel on their H610 spec sheets. So I figure we just give it a day and see who issues a correction.


So this is a typo from Intel by the way. It is dual channel. It should have said 1 DIMM per channel.

@AtenRa The IPC increase isn't enough to overcome a 50% core deficit in the vast majority of cases, including games.

Like I said earlier, the new ADL quads are decent in their own right compared to previous quad cores, but for anyone intending to build a new machine today, I feel the relative small jump in price to an i5 12400/F is more than justified for the performance uplift as well as 'future proofing' - the latest game engines have already moved beyond 4 cores and show significant scaling up to 6 cores. If you are lucky enough to nab a half decent GPU in 2022... do yourself a favour and get a 6 core CPU minimum.

Because of 10nm vs 14nm and also of the huge IPC gains of AlderLake mArchitecture.
...
and
...
Like @epsilon84 said, those IPC increases cannot overcome far fewer cores. I have to ask you again, if there is a 40% IPC improvement per core at the same power level, but one chip has 50% more cores, why would you think the 40% gain would dominate the 50% more cores? If you haven't noticed 40% is smaller than 50%. The fact that the two chips are roughly comparable, shows that Intel's graph of 40% more performance was roughly correct. And that doesn't even include the fact that the 12100 is NOT at the same power consumption.

For the gaming improvement graph, that is a 11th generation i9 vs 12th generation i9. In fact, the 12th generation i9 that does better has more cores to work with and a faster turbo speed. But where this conversation started is an 11th generation i5 vs 12th generation i3 with fewer cores and slower clock frequencies. Thus, I have to ask you why anyone would expect the 12100 to outperform the 11400.

For your argument to even make sense, compare a 12400 to the 11400, not the 12100 to the 11400.

The AL IPC is enough to overcome the 11400 in gaming, it is the horrendous IPC degradation from 12900K to 12100 that makes the 4C 8T CPU not be able to destroy the entry level core i5 11400 in games.

12600K is faster in games vs 11900K, so no problem overcoming the two extra cores of the 11900K.
12400 (18MB L3) should have been equal to 12600K (20MB L3) in gaming but it also exhibits the same Gaming IPC regression as 12100.

The more L3 cache they strip away from the CPU the smaller the performance, when we get down to 4 cores 8 threads CPUs like the Core i3 they have striped away too much Cache and the IPC advantage is gone by by.

I agree with your IPC improvement cannot overcome a 50% core deficit statement.

But, I think we should move past generic statements such as "6 core CPU minimum". It should depend on use cases. If you truly have single-threaded use cases, the 2 core Alder Lake Celeron G6900 can barely beat the 10 core Comet Lake i9 10900K. https://wccftech.com/intels-most-en...ormance-on-par-with-a-5-3-ghz-core-i9-10900k/ If I were to choose a chip today, it would probably be 6 cores (the 12500T seems ideal to replace my HTPC), but I just don't think we should make general statements.

Look above, also

Ryzen 3300X which is only 4 Core 8 Threads completely obliterates the 6-core 12-threads Ryzen 2600X in gaming, it even reaches Ryzen 2700X gaming performance in most of the games.

So for games, priority number one is still the IPC and memory latency and then Core count. And thats true for 4 core 8 threads CPUs and above, otherwise Core i9 9900K would always be faster vs lower count CPUs but as we all know thats not correct.

You forgot #1 priority for games: GPU. Then you forgot #2 priority: clock speed of the CPU of which the 3300X has a higher frequency than the 2600X.

3300X base 3.8 GHz vs 2600X 3.6 GHz.

In games they dont run at base clocks, come on, 3300X has a much higher IPC and lower latencies thats why it can obliterate the 2600X in gaming and not because of the clock speeds.
Same with 12100 vs 11400, the clock difference is 100mhz only.

The 12600K has a ~20% frequency advantage over the 12400 and scores ~10% better in games. How exactly were you expecting a 3.8-4Ghz SKU to equally match one clocked around 4.6-4.8Ghz in gaming?

12600K turbo is up to 4.9GHz when 12400F turbo is up to 4.4GHz, that is only 11% higher clocks. But the performance in gaming in not only due to higher clocks but also due to bigger L3 cache.

I double-checked, the 12600K clocks at 4.5Ghz in games and the 12400 runs at 4Ghz.


OK I did some more research and it seams that 12400F with no power limits (117W TDP) can reach the gaming performance of 12600K at default settings (125W TDP , no PL1 = PL2) .
So I was wrong about the 12400 and 12600K, gaming performance at the same TDP is almost identical.
Question is if we can remove the power limits of locked CPUs on the B660 boards, anyone ???
