Intel’s 12th generation of processors are finally here, along with the new Z690 chipset, and DDR5 memory to go with it. This is truly an exciting time for PC enthusiasts and gamers alike, with the new hardware offering in-game FPS benefits and improved workstation performance. To celebrate this release, we are putting together the best Intel 12th gen DDR5 gaming PC available, giving you a system that can play any game, in any resolution, in max settings.

Intel 12th gen gaming performance

Initial benchmarking data shows that Intels 12th gen gaming performance not only beats AMD’s current series but it also blows the previous Intel generation out of the water. It was never really worth upgrading from 10th gen to 11th gen but now, especially with DDR5 memory, it’s time to upgrade if you want the very best.

Intel 12th gen workstation performance

At this moment in time, the data shows that Intel now provides the best workstation performance in the desktop market. of course, when AMD returns to the table, we expect big things but for now, a Core i9-12900K is going to give you some of the best gaming and workstation performance you can get.

We are going to show our results down below, comparing the Intel Core i9-12900K to its predecessor and the Ryzen 9 5900X.



Benchmark performance Vs AMD Ryzen 9 5900X

We tested the Intel Core i9-12900K with some similar spec parts and an RTX 3090 to show you the comparison between intel 12th gen and Ryzen 5000.

Best Intel 12th gen DDR5 Prebuilt Gaming PC

We understand that not everyone has the skills or time to build a new PC but don’t worry, we’ve found a prebuilt gaming PC with almost identical specifications. This PC will handle everything you throw at it, featuring 32GB of DDR5 memory, an RTX 3080 GPU, and a 2TB NVMe SSD.

Our Recommended Custom Build Details

This Intel 12th gen gaming PC has been designed to bring you the best performance money can buy. We see the power of the brand new Alder Lake flagship processor, DDR5 memory, the Z690 chipset, and RTX graphics in action, giving you high frames across every game.

The new Intel Core i9-12900K is now one of the best processors for gaming money can buy. You are guaranteed blistering desktop performance and incredible FPS in-game, with zero chance of throttling.

Now on the LGA 1700 socket, this i9 features 16 cores and 24 threads and brings in Intel’s latest architecture. The cores are split into eight performance cores and eight efficiency cores and this can hit up to 5.2GHz in boost.

The ASUS ROG Strix Z690-F may not be the best the chipset has to offer but this is well balanced and provides an excellent base for your next-generation components.

This board supports 128GB of DDR5 memory that can run up to speeds of 6400MHz. We also see 16+1 power stages, Thunderbolt 4, PCIe 5.0 support, and Wi-Fi6E. All in all, a great board with impressive connectivity supporting HDMI 2.0 and DisplayPort 1.4 output, quad M.2, USB 3.2 Gen 2×2 Type-C, Type-A, and Front panel USB 3.2 Gen 2×2 Type-C connectors.

The Corsair iCUE H150i Elite Capellix is magnificent for CPU cooling and it achieves this by being virtually silent in the process.

The cooling potential of the H150i matches the competition and this 360mm option is perfect for the Core i9-12900K in this build, with the RGB fans and pump only adding to the overall aesthetics. You may need to contact Corsair for the LGA 1700 cooler bracket upon buying this.

This 32GB kit from XPG offers up a future-proof amount of memory and some impressive speeds to go with. Of course, Intel’s performance doesn’t really dwell on RAM Speed as much as AMD but with this kit, you are set for one incredible system.

The Lancer DDR5 RAM kit comes with two 16GB sticks capable of running at speeds of 5200MHz, so you are never going to be bottlenecked by your RAM.

To match the almighty power of the 12900K, we think an RTX 3080 graphics card is an ideal fit. This highly-regarded GPU features 10GB of GDDR6X VRAM and a very efficient cooling solution. More importantly, this plays any game, in every resolution, no matter the setting, oh and don’t forget ray tracing.

Having fast storage has become quite the gaming necessity, improving load times, boot times, and generally making our lives a lot easier.

This gen4 NVMe SSD is one of the fastest in its class, with read and write speeds of up to 7000/5300MB/ s respectively. We’ve opted for a 1TB model, giving you plenty of room for your operating system, games, and general media files.

Corsair is a huge name in the PC case world and their iCUE 5000X mid-tower is one of the best currently available. Aside from offering high-end build quality and functionality, we have three tempered glass panels and three 120mm RGB fans, giving you the perfect place to house your new build.

Every good PC worth its salt needs a reliable PSU to keep things ticking over. We have a 750W model from Corsair here, with full modularity and a gold-rated level of efficiency, giving you all the reassurance and power you need.

Intel 12th gen gaming PC price

The overall cost can be quite staggering but this is down to the base of this build featuring the next-gen of parts. To save money, you could opt for the lesser-powered Core i7-12700K and pair it with a more affordable Z690. You could also go for a lower-speed RAM kit, while still taking advantage of DDR5, and could grab a cheaper PC case with a more affordable PSU too.

We wanted to build the best Intel 12th gen PC here but we understand that only a minority of gamers can actually afford such luxuries. Another way to save money would be to go for an RTX 3060Ti, however, we wouldn’t recommend pairing this with the i9 CPU shown in the build above, it would be better suited to an i5-12600K.
