Back at CES 2022, which was held in Las Vegas earlier this year, AMD announced that its new Zen 4 core would arrive sometime in the second half of 22. During AMD’s event “together we advance_PCs” live at the At the end of August, AMD introduced its Ryzen 7000 series of desktop processors, with four SKUs targeting different product segments. AMD today officially launched Ryzen 7000 with the Ryzen 9 7950X as the brand representative of performance leadership in an x86 desktop processor.
On paper, the AMD Ryzen 9 7950X is a great 16C/32T to take the overall lead in desktop computing performance. Its entry point to the market is the Ryzen 5 7600X, which has 6C/12T and takes all the advantages of the flagship in a slimmer and more affordable chiplet-based package. AMD is hoping to take back this important performance crown with Zen 4 with its new architecture based on TSMC’s 5nm process; prepare for battle. We’ve detailed what Zen 4 brings to the table in terms of the new microarchitecture, and put the new Ryzen 9 7950X and Ryzen 5 7600X through our CPU suite.
New Zen 4 Core on TSMC 5nm, boost up to 5.7GHz!!
The latest Ryzen 7000 series processors are direct replacements for the Ryzen 5000 series, with a new chipset and newly designed microarchitecture on both the front and back of the silicon design.
As of this writing, AMD is releasing four processors based on its 5nm Zen 4 core, ranging from a 6C/12T to a 16C/32T part; as with previous releases of the Ryzen 5000 (Zen 3) and Ryzen 3000 (Zen 2) series.
The Ryzen 9 7950X: 16 cores, 32 threads, new 170W TDP: $699
Looking at the specs of the four AMD Ryzen 7000 processors, the top SKU is the Ryzen 9 7950X, with sixteen Zen 4 cores (two threads per core, 32T) two eight-core 5nm CCDs. The Ryzen 9 7950X has a base frequency of 4.5 GHz, with a core turbo frequency of 5.7 GHz, which, as it stands, is the world’s fastest CPU core for the desktop space current
AMD has also given the Ryzen 9 7950X a higher TDP of 170W, which compared to its Ryzen 5000 counterpart, the 5950X, is an increase of 65W (170W vs. 105W). This increase in overall power has allowed AMD to improve its frequencies. , as well as giving its Precision Boost Overdrive overclocking technology more room to breathe; more power usually means more performance.
The Ryzen 9 7900X, Ryzen 7 7700X and Ryzen 5 7600X
Moving up the stack is the Ryzen 9 7900X, which is a 12C/24T, 170W TDP piece; it has a higher base frequency than the 7950X at 4.7GHz, but with a slightly lower boost frequency of up to 5.6GHz. AMD has released a Ryzen 7 part designed for mid-range desktop computing, through the Ryzen 7 7700X, which is an 8C/16T SKU, with a single-core boost frequency of up to 5.4 GHz, with a base frequency of 4.5 GHz. .
Focusing on the entry segment, its Ryzen 5 7600X seeks to capitalize on offering 6C/12T with its previous series maximum TDP or 105W, at a reasonable price. The Ryzen 5 7600X features a base frequency of 4.7 GHz, with a modest boost frequency (compared to Ryzen 9) at a single core of 5.3 GHz.

Comparing apples to apples, so to speak, from the new Zen 4 generation to the previous Zen 3 generations with similar products, Ryzen 7000 has made some significant overall improvements to the chip’s capabilities. Starting at the top tier, the Ryzen 9 7950X has a huge improvement in base and boost frequencies, making Zen 4’s efficiency better than any previous generation of Ryzen.
This has been made possible in part by superior power efficiency, as the Zen 4 item is largely a refinement of the Zen 3, but produced on TSMC’s 5nm process node (up from TSMC 7nm). This efficiency has allowed AMD to increase clock speed without breaking the power bank, with the 105W TDP 7700X seeing a 700MHz improvement with no change in TDP. Coupled with a 13% TDP improvement, and Ryzen 7000 series chips can deliver significant single-threaded performance gains. And multi-threaded performance isn’t neglected either; by increasing its TDP above 170W, AMD is able to keep the CPU cores of its 12C and 16C parts at more sustained turbo clocks, delivering much better performance there as well.
Of course, one of the key arguments here is that more power equals more, which is true of the Ryzen 7000 series. Ryzen 7000’s TJ Max for its Precision Boost Overdrive technology is 95°C, the which means the CPU will use all available thermal space to maximize performance.
While this can be overridden when manual overclocking, this opens up the maximum TJ Max to 115°C. It’s key to note that users will need to use more premium and aggressive types of cooling to squeeze every last drop of performance out of Zen 4. AMD takes into account the fact that Ryzen 7000 runs hot through its design choices and implementations. As such, they’ve chosen not to bundle their own CPU coolers with the retail bundles, instead directing buyers to fairly powerful third-party coolers.
New AM5 socket: AM4 coolers will also support AM5
AMD has also transitioned to a new chipset for Ryzen 7000, called AM5. Along with AM5 also comes a new socket, the LGA1718. Now what’s interesting is that AMD has specified that most coolers with an AM4 socket will support the new LGA1718 socket in AM5; this is great for maintaining previous generation compatibility.
This also means that AM4 is now a thing of the past, although it offers something incredible at the moment, as well as support with the cheaper DDR4. Of course, AMD has switched to support for DDR5 memory, with the JEDEC settings on all four CPUs set to DDR5-5200; an improvement in Intel’s 12th Gen Core series support for DDR5-4800.
AMD has introduced four new chipsets, two Extreme variants named X670E and B650E, with two regular chipsets, aptly named X670 and B650, original and simple. The higher-end X670E series will feature both PCIe 5.0 lanes in the top PEG slot, with support for PCIe 5.0 storage devices expected in November 2022. As for its regular X670 chipset, PCIe 5.0 in the PEG slot is optional, not required. as in X670E.
The B650 chipsets are designed to be more affordable and therefore only include PCIe 4.0 lanes in the PEG slot. However, they do have at least one PCIe 5.0 x4 storage slot. The B650E is reserved for those low-end boards that want to include PCIe 5.0 on the graphics card, although users looking to use PCIe 5.0 support should opt for the X670E; better boards, better drivers and better specs.
New I/O die: TSMC 6nm for Ryzen 7000
As we’ve seen previously in the Ryzen 5000 series, AMD uses a chiplet package, with two complex core (CCD) arrays in its top SKU, with an I/O array housing all of the PCIe 5.0, the integrated memory (IMC), and new for Ryzen 7000, two AMD rDNA 2 integrated graphics CUs. Some of the key benefits of AMD’s new 6nm TSMC I/O die mean more transistors, better efficiency at the manufacturing stage, and ultimately most important of all, from a of efficiency, lower overall energy consumption.
