Pros: Noticeably faster and able to handle more tasks than previous cpu.
Overall Review: Glad I paid extra for this cpu. Ibe got zero buyers remorse on this purchase.
Pros: Going from an 8th gen to 12th was night and day difference. Worth it!!
Cons: A bit pricey
Overall Review: Benchmarks nicely.. buy it, you wont regret it!
Pros: - Fast, Fast, Fast! Lives up to it's reputation.
- Runs relatively cool in my setup. After reading reviews I was expecting it to run hotter in stock configuration (I am not overclocking).
- Latest and greatest. Support for DDR5 and PCIe 5.0 when those become a thing.
Cons: None really. Cost? Sure it's a little pricey but if you want the best....Early adopters and enthusiasts always pay more. To each their own I guess. If you want to save some dough then get the 12700K- it will still perform well, but it just won't be the best as of today.
This is not a con per se, but while I love the packaging for it's looks and feel, I wonder how much cost Intel could save by using plain Jane packaging and pass that savings to the consumer. Maybe it's just pennies anyways, who knows.
Overall Review: I am a middle aged guy, novice builder and my midlife/COVID crisis was building a top of the range computer so I did. I am not a serious gamer and mainly play race sims and flight sims (F1, Project Cars, MSFS2020, XPlane etc) and I run stock settings on everything. I sometimes edit video clips for personal use and I'm definitely not a pro. I have daily driven this setup for about a month now and here's what I found out:
It would be an understatement to say that coming from a I7-6800K, this CPU just crushes everything I throw at it. Rendering a 4K clip that used to take around 10 minutes now takes about 10 seconds! And as far as temps go, idle temps are 30C and during gaming sessions the CPU runs below 70C, and although it spiked to 93C at the start of CinebenchR23 runs before the fans kicked in, it averaged 80C during those tests where best score was 27104 which seems pretty good. I am using 360AIO cooler. Max CPU power draw was 232W during stress tests. From what others have said, I expected this PC would be a heat pump in my room, but that has not been my experience. The ambient room temps have gone up a couple degrees to 72F/22C, but it has also been triple digits in Chicago lately so I say that's a wash. The temps coming out the top of my (closed) Lian Li Dynamic EVO case during stress tests was 84F/29C.
Other thoughts- Being the novice I am, I read many reviews and watched countless YT videos on this CPU and my other components and it seemed that I would need to mess with BIOS settings to change voltages and profiles because of the thermal issues. But I wanted to run everything stock so that I could find out if an "average" user like me could just drop it in and make it all work and work well. I think it does, and if that helps another builder like me assuage their fears of messing with the BIOS and just see it work with no hassles, then all the better. At this point I would have to think that all the others out there that have thermal issues either had defective or substandard CPU's, or there were other issues with components or assembly of said components. I think each system is different, and people don't always follow the same procedures. I also heard about the DDR5 issue when 4 sticks are used. I used (4) 32GB sticks in stock 4800Mhz trim and it worked from the first boot, so there again, it can be done and to be fair, I think those other issues stemmed from trying to OC in the XMP profile. If you can live with a clock speed just a little lower, 4 sticks will work.
Bottom line- This CPU is a beast. I have not run into thermal issues with my stock setup. I would highly recommend it to anyone who wants (or can afford) the best. You will not be disappointed. But do your research on your build components for compatibility- some things just work with others and some don't. Maybe I got lucky that mine all worked from the jump. Your mileage may vary.

Pros: Mix of P and E cores is a great improvement.
Runs actually quite cool, much better than expected (I'm not overclocking).
Can see a noticeable improvement over the i9-10900.
Cons: To take full advantage of the processor you need Windows 11, which unfortunately is significantly stripped down compared to Windows 10 and not meant for power users. Not Intel's fault, so I'm not taking any points off.
Overall Review: I was really impressed with how much this is an improvement over the 10th gen processors. Everything is faster in comparison and it's actually noticeable.
Pros: Handles virtualization well. I have been using it to simulate a datacenter network topology.
The price isn't terrible for what you get.
Cons: Hard to think of any.
Overall Review: I'd totally recommend this part.
Pros: This CPU is fast and is running on the LGA1700 socket that is anticipated to be compatible with Raptor Lake and Meteor Lake future CPUs!
Overall Review: This new intel 12900 CPU was a pretty good increase in performance over my previous 10980XE 18 core extreme CPU and comes with additional capabilities such as PCIE 5.0 and DDR5!
Updated pictures, dark orange is CPU out of box with memory manually overclocked for 4 sticks of DDR5 RAM @ 5200MHz using 6000MHz capable RAM. Bright orange is with same RAM settings but CPU with AI overclock at 5.3GHz.
Pros: When stress tested it runs at round 70-78 under full load with an air cooler (noctua)
Cons: Non yet will update the review in a year or so
Overall Review: Finally a Good intel processor
Pros: -Solid single core and multicore performance
-With Ai overclocking easily reached 5.4ghz all cores
-Idle temps 30-35C
-Load temps 50-70
-Really cool box
Cons: -Small Heat spreader without specific coolers this cpu could easily overload most coolers
-Nothing else I can think of
Overall Review: I would recommend this cpu to anyone wanting to get the best performance as of this review. With the right motherboard and cooler combo this cpu destroys every game or software I throw at it. I am aware that it produces a ton of excess heat in very high workloads. In more realistic and in my own testing, It draws less power then my previous 5820k. Keep in mind this cpu should be water-cooled and you will have a great time!
