Intel Core i7-12700K

[Minus Infinity]

I wonder what effect high DDR4 bandwidth & timings has on rocket lake with all these tests in comparison to alder lake with DDR5?
Also difficult to tell what effect win 10 has on all these tests too...
Some more variable to throw into the mix... oh the joys of I.T !

Well Anadtech has shown the effects of DDR4 vs DDR5 on the 12900K and it's only in high band-width multi-threaded tasks the DDR5 makes a difference and only in a few cases. High prices and high latency low speeds are why I am waiting for RL. In 12-15 months I expect a lot more choice and compelling products and hopefully more sensible prices on DDR5 to make it a worthwhile purchase.

Um, why is Intel the evil empire? Seem like fanboying going on there..

well, for my point of view..... galactic empire by sith lord, is the best of the best empire in all universe.........including this new alder lake series by intel cpu..... ^^

 

[AlwaysHope]

My guess? DDR4 would not degrade performance much if at all. These new CPUs don't seem RAM speed bottlenecked/dependent/limited given the reviews elsewhere on the net.

The testing here was done with DDR5-6000 & compared with DDR4-3600, where as the default RAM speeds should be DDR5-4800 & DDR4-3200.

Results here demonstrate OC memory & by a large margin indeed, 2,400MHz to be precise. I'd also prefer testing done with Win10 & then 11 to compare side by side.

Just ordered a 12700K with Asus Prime P Z690 DDR4. That board is all I need. Ill get a DDR5 board when it matures. Board will match my Brushed Aluminum HTPC case.

Do I need it? No

Do I want it? Yes

Do I love hardware? Yes : )

True, but DDR4 has tighter timings. The perfomance gap is never very big from one type of RAM to another during a generation jump. History has proven this.

 

[W1zzard]

Yes, but I have to update my testing software with support for Alder Lake first.

I imagine that is a real problem for most testers and reviewers..

not really .. unless they write their own software. Update in that context means I need to look at the code for my in-house "turbo frequency test" and change it so that it reports ADL results correctly and P/E cores separately

Ah, ok. I see what you mean. Thought you were talking about benching/testing software in general and needed to grab updates as they come out. A number of benching/testing suites have been having a few issues and need updating.

 

[GhostRyder]

Well very interesting results, definitely high performance and I really like the idea. However, that power consumption... The overclocking really punched the power consumption and temps. I really want to see what it would do under my LC loop.

 

[FeelinFroggy]

Maybe its time I replace my good old 8700k. I would see a decent framerate boost.

Yes but also need to factor in bios maturity on the relevant platforms. It's never an apples to apples comparison, no matter who the reviewer is or are.

I will be undervolting at any given speed. No power or heat problems for me : )

Good point. Still, I think it was wise for Intel to support both types of RAM. It makes the price of an upgrade path much easier because a lot of people can reuse their existing RAM.

Most certainly, but I think DDR4 will gimp AL performance somewhat. Reminds me of the days when Phenom II had the dual DDR2/DDR3 IMC. The best of that chip was seen with DDR3.

I don't think that is going to happen. The current benchmarks all over the net certainly are not showing that.

While true, that was only with DDR3-1333 and up. DDR3-800/1066 did not compete well with DDR2-667 or 800. DDR3-1333 didn't start hitting shelves until 2 years after DDR3 hit the market. The same thing happened with Socket775. It wasn't until 1333 & 1600 did DDR3 pull away from DDR2 in performance. We're not going to see DDR5 take the lead until the 6000mhz kits are commonly available. Until then higher-end DDR4 will be the better choice.

Yes, I should have been more specific with bandwidth speeds.

Yep can't wait to see the difference from my old 7700K to 12700K, should be a huge jump.

Oh goodness yes. That'll be a huge jump! That's like jumping from Pentium D to Core i7-920.

Review of the 12700K.

Spoiler: Intel Core i7-12700K & 12700KF CPU Review, Benchmarks, & Efficiency vs. AMD Ryzen

 

[RobertR]

Indeed (on the expected large perf boost): I am replacing my almost-5-years old [non-K] Core i7-7700 with the 12700K!

I wouldn't be purchasing a "K" model now if I wouldn't have to wait an unspecified amount of time for the 12700.

I already have the 850W SeaSonic PS, the Fractal Design Define 7 case, and oh yes, an RTX 3070 - just waiting for the 12700K, and I am going for a Gigabyte Aorus Master - both of which are in the mail (literally), but the rub of course, is the G.Skill with tighter timings Z5 RGB DDR5. Sigh.

I am planning on using a Noctua NH-D15S (the "S" means only one fan, reducing the weight but not losing too much of the cooling capacity) - does anyone see an issue with this cooling solution for the 12700K? I was thinking about a 280mm AIO, but as I stubbornly insist on having an optical drive, there doesn't look to be quite enough room along the top inside of the case for the radiator (it's close).

Finally, should I be concerned about the weight of the Noctua? Intel sorta says that the max weight of the cooler is like 950 grams, whereas the Noctua NH-D15S is a little over 1.1 kg... I would think that Gigabyte would reinforce the socket area of a mobo this expensive, but?

I plan on upgrading my 4790K as well. I'm still deciding between 12700K and 12900K.

- both CPUs have same number of P-Cores, and games "should" only run on P-Cores. For incompatible games, most motherboards have option to disable E-Cores. This makes me want to go for 12700K.

- looking at Intel's roadmap, the 13th gen will keep the 8 P-Cores and double the number of E-Cores, that means E-Cores will play a more important role down the road. That makes me want to go for 12900K.

For my old 4790K, either one will be a huge upgrade. I already placed order on 12900K (thanks Best Buy for not gouging the price), but still debating if I should cancel and get 12700K instead...

PLEASE, PLEASE, PLEASE do a video about HOW you've fit the Arctic Liquid Freezer II 360 with the retrofit kit that we can order from Arctic. I've the exact same CPU but with ASUS ROG Strix Z690-A Gaming WiFi D4.
It seems that you'ce put the O-rings on TOP? But it's totally different in Arctics so called "manuall" I post the link to it and how it looks from my Reddit post. PLEEEEEEASE help. THANKS

you're having bad contact problems? bottom of the pump ends up sitting on a capacitor. just screw off the plastic cover

Thank you, but no I'm not there. The backplate nuts are not coming through the MOBO. They are barely even. But I see that the Techpowerup have the O-rings on the CPU side of the MOBO (it seems), but in the SH*****Y) "manuall of Arctic they have the O-rings the backplate nuts and on the back.!?
VERY confusing "manual" and first if you lok at the "preparation" you see something and then "installation" you see something else. SO MAD

The backplate fits through just fine here. I just moved the o-rings to the other side, so they hold down that backplate a little bit and it's easier to screw in the posts from the other side. This system sucks and I've shared that feedback with Arctic

Which MOBO? So you moved the O-rings to the "top" where the CPU is? Does DUMB ASS Backplate nuts are way to short man. . I just ordered the Corsair iCUE H150i ELITE CAPELLIX, payed 2,99 for the Retro fit and hopefully I'll NEVER have to see Arctics STUPID A** cooler. I tried as hard as I could without breaking my brand new DAMN MOBO. One of the standoffs where NEVER standing uppright, it was always leaning.
It's a shame becuase I really wanted it.

DAAAAAAAAMN STUPID ARCTIC. I'll return my STUPID Arctid BS "cooler"
