AMD Zen 4 Ryzen 9 7950X and Ryzen 5 7600X Review: Retaking The High-End

At the beginning of the year at CES 2022 in Las Vegas, AMD announced that the new Zen 4 cores would be arriving in the second half of 2022. At the end of August, AMD announced his Ryzen 7000 series desktop processors. It has four of his SKUs aimed at different product segments. Today AMD officially unveiled his Ryzen 7000. The Ryzen 9 7950X represents a brand of performance leadership in desktop x86 processors.

On paper, the AMD Ryzen 9 7950X is a 16C/32T behemoth and the overall performance leader in desktop computing. Their entry point to the market is the Ryzen 5 7600X, which features 6C/12T and utilizes all the benefits of the flagship in a sleeker and more affordable chiplet-based package. With Zen 4 featuring a new architecture based on TSMC’s 5nm process, we’re looking to restore the all-important performance crown. Prepare for battle. We’ve detailed what Zen 4 brings to the table in terms of the new microarchitecture and tested the new Ryzen 9 7950X and Ryzen 5 7600X through the CPU suite.

TSMC 5nm’s New Zen 4 Cores Boost Up To 5.7 GHz!!

The latest Ryzen 7000-series processors are direct replacements for the Ryzen 5000-series, featuring a new chipset andel as a newly engineered microarchitecture on both the front-end and back-end of the silicon design.

At the time of writing, AMD has launched 4 processors ranging from 6C/12T to 16C/32T based on 5nm Zen 4 cores. Similar to the previous Ryzen 5000 (Zen 3) and Ryzen 3000 series (Zen 2) launches.

Ryzen 9 7950X: 16 cores, 32 threads, new 170W TDP: $699

Looking at the specifications of the four AMD Ryzen 7000 processors, the top SKU is the Ryzen 9 7950X which features 16 Zen 4 cores (2 threads per core, 32T) with an 8 core 5nm CCD. The Ryzen 9 7950X has a base frequency of 4.5 GHz and a single core turbo frequency of 5.7 GHz, making it the world’s fastest CPU core in the current desktop space.

AMD also gave the Ryzen 9 7950X a TDP of 170W. This is a 65W increase when compared to its Ryzen 5000 counterpart, the 5950X (170W vs 1Thisn) This overall power increase has allowed AMD to improve their frequencies. As well as giving the Precision Boost Overdrive overclocking technology room to breathe, more power usually means more performance.

Ryzen 9 7900X, Ryzen 7 7700X, Ryzen 5 7600X

Moving down one in the stack is the Ryzen 9 7900X, which is a 12C/24T and 170W TDP part. The base frequency is higher than the 4.7 GHz of the 7950X, but the boost frequency is slightly lower with a maximum of 5.6 GHz. AMD has launched one Ryzen 7 part designed for mid-range desktop computing with the Ryzen 7 7700X. .

Focused on the entry-level segment, the Ryzen 5 7600X looks to leverage the previous series’ max TDP o 105W to offer 6C/12T at an affordable price.The Ryzen 5 7600X has a base of 4.7 GHz It has a modest (compared to Ryzen 9) boost frequency with a single core of 5.3 GHz.

Going apples to apples, so to speak, from the new Zen 4 generation to the previous Zen 3 generation, the Ryzen 7000 makes some significant spec improvements across the board. The top-of-the-line Ryzen 9 7950X has a big advantage in base and boost frequencies, so Zen 4’s efficiency is better than any previous Ryzen generation.

This is due to better power efficiency as Zencally is an improved version of Zen 3 but based on the new TSMC 5nm process node (from TSMC 7nm). This efficiency allowed AMD to increase the overall TDP from the previous 105W to 170W, but without a big penalty.

Of course, one of the key arguments here falls on the Ryzen 7000 series path. Ryzen 7000’s Precision Boost Overdrive technology has a TJ Max of 95°C, which means the CPU uses all available thermal headroom to maximize performance.

This can be overridden by manually overclocking with a maximum TJ Max of up to 115°C, but it’s up to the user to squeeze the last drop of performance out of the ZAMD that was intended when designing Zen 4 at a premium. It is important that the active cooling type should be used. That’s why we chose not to bundle our own CPU cooler with the retail package.

New AM5 socket: AM4 coolers also support AM5

AMD has also moved to a new chipset for Ryzen 7000 named AM5. In addition to AM5, it also comes with a new socket called LGA1718. What’s interesting here is that AMD specified that most of his AM4 socket coolers support his LGA1718 socket, which is new to his AM5. This is great for maintaining compatibility from previous generations.

This also means that AM4 is a thing of the past, although AM4 now offers some great features, DDR4 is also retained. A,MD of course switched to DDR5 memory support with JEDEC settings on all 4 CPUs set to DDR5-5200. Improved Intel 12th Generation Core Series support for DDR5-4800.

AMD has announced four new chipsets, two Extreme variants named X670E and B650E and two original and simple regular chipsets aptly named X670 and B650. The top-of-the-line X670E series features both PCIe 5.0 lanes to the top PEG slot along with support for PCIe 5.0 storage devices expected in November 2022. For regular X670 chipsets, PCIe 5.0 to PEG slot is optional and not required. Like X670E.

The B650 chipset is designed to be more affordable, so it only has PCIe 4.0 lanes to PEG slots. However, it does have at least one PCIe 5.0 x4 storage slot. The B650E is reserved for low-end boards that want PCIe 5.0 built into their graphics card, while users who want to take advantage of PCIe 5.0 support should opt for his X670E. Better boards, better controllers, and better specs.

New I/O Die: TSMC 6nm for Ryzen 7000

As we’ve seen before with the Ryzen 5000 series, AMD will use a chiplet package, with its top SKU having two Core Complex Dies (CCDs), the I/O dies all PCIe 5.0, an integrated memory controller ( IMC). , and two of his CUs of AMD’s rDNA 2 integrated graphics, new to Ryzen 7000. Some of the key benefits of AMD’s new 6 nm TSMC I/O die are more transistors, more efficiency at the manufacturing stage, and finally, most importantly, from an efficiency standpoint, an overall It means less power consumption.
