Since Intel announced and launched its 12th Gen Core series of CPUs in to the market, we've reviewed both the flagship Core i9-12900K, as well as the entry-level (but still very capable) Core i3-12300 processors. Today, we're looking at the middle of the stack, with the Core i7-12700K and Core i5-12600K both taking center stage.

Ever since AMD launched its Zen 3 architecture and its Ryzen 5000 series for desktop, Intel has been playing catch up in both performance and pricing. Intel's hybrid Alder Lake design is its second attempt (Rocket Lake) to dethrone Ryzen 5000 as the go-to processor for consumers building a high-end desktop system for gaming, content creation, and everything in between. It's time to see if the Core i7-12700K and Core i5-12600K can finally level the playing field, if not outright give Intel an advantage in the always popular mid-range and enthusiast markets.

Below is a list of our detailed Intel Alder Lake and Z690 coverage:

As a quick recap, we've covered Alder Lake's dual architectural hybrid design in our Core i9-12900K review, including the differences between the P (performance) and E (efficiency cores). The P-cores are based on Intel's high-performing Golden Cove architecture, which provides solid single-threaded performance. Meanwhile, the Gracemont-based E-cores, although lower-performing on their own, are smaller and draw much less power, allowing Intel to pack them in to benefit multi-threaded workloads without blowing the chips' power and thermal budgets.

Intel 12th Gen Core i7 and Core i5 Series: For The Mid-Range & Enthusiasts

At the beginning of 2022, Intel unveiled 22 new Alder Lake Desktop-S processors to the market, with the K-series processors such as the Core i9-12900K, Core i7-12700K, and Core i5-12600K having been made available back in November 2021. Looking at Intel's 12th Gen Core i7 lineup, there are five SKUs in total, all of which are variants of the 12700 offering the same 8 P-cores and 4 E-cores at different clockspeeds and TDPs. Leading the group are the Core i7-12700K and i7-12700KF, which come with an unlocked multiplier and can be overclocked when used with a Z690 motherboard.

The Core i7-12700 is a base model with no overclocking support, while the Core i7-12700F is the same as the base model without the integrated Xe Iris graphics. The last of the Core i7 models is the i7-12700T, which has a lower base TDP of 35 W, with a turbo TDP of 180 W and a P-Core turbo of 4.7 GHz primarily designed for low powered systems.

i5-12400T 6+0 - - 1800 4200 18 730 35 74 $192

Moving onto the 12th gen Core i5 series, there's a total of nine SKUs, which is a large stack for the mid-range market. Prices range from $289 for the top SKU, the Core i5-12600K with an unlocked multiplier and full overclocking support, and the Core i5-12600KF ($264), which is the exact specification minus Intel's Xe integrated graphics.

Out of all of Intel's 12th Gen Core i5 series parts, the Core i5-12600K and i5-12600KF are the only two chips to include both P-Core (Golden Cove) E-Core (Gracemont) hybrid cores. They both feature six P-cores four E-cores, for a total of 16-threads. The rest of the Core i5 stack for Alder Lake includes only six P-cores based on Intel's Golden Cove architecture, foregoing the E-cores entirely.

There are three 'base' models of the Core i5, including the i5-12600, i5-12500, and i5-12400, with differences only in base frequency and turbo frequencies (and price), with just $31 separating them in 1K unit pricing. Intel also has three T series variants, including the Core i5-12600T, the i5-12500T, and i5-12400T, all with a base TDP of 35 W and a turbo TDP of 117 W. There's also an odd one out, the Core i5-12400F, which is the same specifications as the Core i5-12400 base model, but without integrated graphics.


Intel Laminar RM1 Stock CPU Cooler for non-K Core i7, Core i5, and Core i3 processors

As we highlighted in our Core i3-12300 review, Intel has also refreshed its 'stock' coolers for the first time in what feels like an age. Accompanying all of Intel's 12th Gen Core i7, Core i5, and Core i3 processors (not the K/KF SKUs) is the Intel Laminar RM1 stock CPU cooler, which has a revamped design over previous iterations of its stock cooler. The Laminar RM1 is constructed of a copper base with aluminum fins and is designed to support up to and including 65 W TDP processors.

The Intel Core i7-12700K & Core i5-12600K: Market Positioning and the Competition

For the first time since AMD released its Zen 3 based Ryzen 5000 series desktop processors, Intel has undoubtedly been playing catch up. Its 11th Gen Core (Rocket Lake) architecture bridged the gap somewhat, but as seen in our initial review of Alder Lake via our Core i9-12900K review, only with their latest generation of chips has Intel been able to leap-frog ahead of AMD at the top of the desktop CPU market. 

Looking at where the 12th Gen Core i7-12700K slots in, it has 8+4 (12) cores for 20 threads, and as such, it competes against the AMD Ryzen 9 5900X, which has 12-Zen 3 cores and 24 threads. Especially following some very recent tightening of the market for AMD chips, the Core i7-12700K has become a much better deal on paper with a current selling price at Amazon of $400 versus the $480 that the Ryzen 9 5900X currently costs.

The Core i5-12600K is slightly different, as it has two main rivals on the market, the AMD Ryzen 7 5800X with 8 cores and 16 threads for $390, and the Ryzen 5 5600X, which can be purchased at Amazon for $229 at present. In contrast, the Core i5-12600K has a hybrid 8+4 (12) core design for 16 threads, and it fits in between both of these in the market with a current selling price at Amazon of $279.

 

Despite many design differences between the aforementioned chips, including core count, thread count, architecture, and core structure, the only differences many are likely to care about are the performance and the price. Earlier this month AMD cut pricing on virtually all of its Ryzen 5000 line-up, which made things much more competitive when comparing Intel's 12th Gen Core MSRP versus AMD's Ryzen 5000's initial launch MSRP. However a very recent bounce in AMD chip prices has started to undo this.

 

Another variable to consider in this market segment is AMD's new Ryzen 7 5800X3D, with 3D V-Cache, which targets gamers, 8-cores, 16-threads, but it isn't overclockable. AMD intends to launch it on April 20th, and the Ryzen 7 5800X3D will launch with an MSRP of $449. This roughly coincides in terms of pricing with its Ryzen 9 5900X, and is $50 more expensive than the Core i7-12700K, which benefits from more cores and faster cores...and it's overclockable.

Test Bed and Setup

Although there were some problems initially with the Intel Thread Director when using Windows 10 at the launch of Alder Lake, any core scheduling issues are entirely negated by using the latest Windows 11 operating system. The Intel Thread Director works in tandem with Alder Lake to assign the right P-cores and E-cores to different tasks based on the complexity and severity of the workload. We are also testing the Core i7-12700K and Core i5-12600K with DDR5 memory at JEDEC specifications (DDR5-4800 CL40). We are also using Windows 11, which we are using now for CPU and motherboard reviews as we advance into the rest of 2022 and beyond.

For our testing, we are using the following:

Alder Lake Test System (DDR5)
CPU Core i5-12600K ($289)
6+4 Cores, 16 Threads
125W Base, 150W Turbo

Core i7-12700K ($409)
8+4 Cores, 20 Threads
125 W Base, 190 W Turbo
Motherboard MSI Z690 Carbon WI-FI
Memory SK Hynix
2x32 GB
DDR5-4800 CL40
Cooling MSI Coreliquid 360mm AIO
Storage Crucial MX300 1TB
Power Supply Corsair HX850 
GPUs NVIDIA RTX 2080 Ti, Driver 496.49
Operating Systems Windows 11 Up to Date

All other chips for comparison were run as tests listed in our benchmark database, Bench, on Windows 10.

    > Intel would collapse under the weight of its own cost structure built around those fabs

    It wouldn't have to be overnight, and obviously they'd have to rationalize some aspects of the business. However, it seems like the right thing to do, especially if there are activities they couldn't undertake without manufacturing in-house. That just screams either "inefficiency" or, more likely, "unfair advantage".

    The one thing I don't accept is that "it has to be this way, because it always was". That's almost never a good reason not to change something.

    "That just screams either "inefficiency" or, more likely, "unfair advantage".

    I agree, both, there are many inefficiencies in enterprise and industry relations, and governance and oversight.

    "Always was", the inefficiency is being addressed for a very long time! It's just the way things have worked out over 24 years to resolve Intel inefficiencies that are not effective under democratic capitalism caught in associate network conundrums. mb

    "Because it quite literally cannot be both."

    It literally can given that Intel only started adding more than 4 cores after Ryzen launched and then, subsequently, had to blow their power requirements out just to keep up... and you're reaching all the way back to 'dozer - a CPU designed long after AMD had relinquished leadership - to try to bat back the valid accusation that Intel have always abused their leadership position to rinse consumers.

    And CUDA isn't vendor lock-in?
    GPU compute is a great idea -- and that's not just my opinion. AMD failed to deliver in a big way when it came to getting CPU/ GPU sharing compute capabilities off of the ground. They're still working on it (CDNA...). But it's unlikely at this point to be available to us -- which is what I dislike.

    Yeah, HSA really fizzled and even the original APU & fusion concept as some kind of synergistic processing unit went sideways.

    Then, AMD got distracted by AI and became consumed by chasing Nvidia in that market and HPC. The consumer platform has been largely neglected by them, since.

    Nonsense. Fusion culminated into APUs and is one of the biggest successes of AMD ever, please talk and comment less, you’re a huge wannabe. Reply

    > Fusion culminated into APUs and is one of the biggest successes of AMD ever,

    What I mean is that "Fusion" turned out to be a marketing thing. The idea of using iGPUs as a compute accelerator didn't really go anywhere.

    AMD jumped from backing OpenCL to HSA, thinking that would spur industry adoption, but it fizzled even worse than OpenCL (which has continued plodding along, in spite of loss of interest/support).

    Microsoft is even discontinuing C++ AMP.

    > please talk and comment less, you’re a huge wannabe.

    Please troll less. News comments were fine without you. I have yet to see you add anything of value. Mostly, you just seem to antagonize people, which is the very definition of trolling.

    I meant AMD's loss of interest/support. Heck, even Nvidia has gotten on board with 3.0!

    It's hard not to agree.
    These Intel 12th-gen products are a 2022 product and should be compared with a 2022 alternative. Besides they're somewhat of a paper launch, anyway. AMD has a lot of headroom to turbo boost solo core, add more cores, increase thermal headroom, add faster memory..... without having to do major overhaul on Zen3 architecture. They have somewhat rested on their laurels with Zen3, but I suspect that Zen4 is going to be a very distinct uplift. The way the companies stack is:

    2017 Zen1 vs Intel 7th-gen
    2018 Zen+ vs Intel 8th-gen
    2019 Zen2 vs Intel 9th-gen
    2020 Zen3 vs Intel 10th-gen
    2021 Zen3. vs Intel 11th-gen
    2022 Zen4 vs Intel 12th-gen

    PS: both AMD Zen2 and Intel 10th-gen are significantly slower in single-core, multi-thread, and use much more energy than Apple M1 chips. Things look a bit more even with Zen3 and Intel 11th-gen. But the Apple M2 chips will likely "humiliate" the likes of Intel 12th-gen and AMD Zen4. But then again this is comparing Apple's to Windows, so a moot point.
