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

1 year ago 33

Back astatine CES 2022, which was held successful Las Vegas earlier astatine the opening of the year, AMD announced that its caller Zen 4 halfway would beryllium coming sometime successful the 2nd fractional of 22. During AMD’s ‘together we advance_PCs’ unrecorded streamed lawsuit astatine the extremity of August, AMD unveiled its Ryzen 7000 bid of desktop processors, with 4 SKUs aimed astatine antithetic merchandise segments. Today AMD has officially launched Ryzen 7000 with the Ryzen 9 7950X sitting arsenic the brand’s typical of show enactment successful an x86 processor for desktops.

On paper, the AMD Ryzen 9 7950X is simply a 16C/32T behemoth to instrumentality wide show enactment successful desktop computing. Their introduction constituent into the marketplace is the Ryzen 5 7600X, which has 6C/12T and harnesses each the benefits of the flagship successful a much svelte and affordable chiplet-based package. AMD pins its hopes connected bringing that all-important show crown backmost to its broadside with Zen 4 with its caller architecture based connected TSMC’s 5 nm process; hole for battle. We’ve elaborate what Zen 4 brings to the array regarding the caller microarchitecture and tests the caller Ryzen 9 7950X and Ryzen 5 7600X done our CPU suite.

New Zen 4 Core connected TSMC 5nm, Boost Up to 5.7 GHz!!

The latest Ryzen 7000 bid of processors are nonstop replacements to the Ryzen 5000 series, with a caller chipset andell arsenic a recently designed microarchitecture some connected the beforehand and backmost extremity of the silicon’s design.

As it stands astatine the clip of writing, AMD is launching 4 processors based connected its 5nm Zen 4 core, ranging from a 6C/12T portion each the mode up to 16C/32T; conscionable similar with the erstwhile Ryzen 5000 (Zen 3) and Ryzen 3000 bid (Zen 2) launches.

The Ryzen 9 7950X: 16 Cores, 32 Threads, New 170 W TDP: $699

Looking astatine the specifications of the 4 AMD Ryzen 7000 processors, the apical SKU is the Ryzen 9 7950X, with sixteen Zen 4 cores (two threads per core, 32T) 2 eight-core core 5nm CCDs. The Ryzen 9 7950X has a basal frequence of 4.5 GHz, with a turbo frequence connected 1 halfway of 5.7 GHz,, which arsenic it stands, is the fastest CPU halfway successful the satellite for the desktop abstraction today.

AMD has besides fixed the Ryzen 9 7950X a larger 170 W TDP, which erstwhile compared to its Ryzen 5000 counterpart, the 5950X, is an summation of 65 W (170W versus 105W) This increase successful wide powerfulness has allowed AMD to amended connected its frequencies, arsenic good arsenic giving its Precision Boost Overdrive overclocking exertion much country to breathe; much powerfulness typically means much performance.

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

Moving 1 down the stack is the Ryzen 9 7900X, which is simply a 12C/24T and 170W TDP part; it has a higher basal frequence than the 7950X of 4.7 GHz, but with a somewhat little boost frequence of up to 5.6 GHz.  AMD has launched 1 Ryzen 7 portion designed for mid-range desktop computing, done the Ryzen 7 7700X, which is an 8C/16T SKU, with a boost frequence connected a azygous halfway of up to 5.4 GHz, with a basal frequence of 4.5 GHz.

Focusing connected the entry-level segment, its Ryzen 5 7600X looks to capitalize connected offering 6C/12T with its erstwhile bid maximum TDP o 105W, astatine a tenable terms point. The Ryzen 5 7600X includes a basal frequence of 4.7 GHz, with a humble (compared to Ryzen 9) boost frequence connected a azygous halfway of 5.3 GHz.

Comparing apples to apples, truthful to speak, from the caller Zen 4 procreation to the erstwhile Zen 3 generations with like-for-like products, Ryzen 7000 has made immoderate large wide improvements to the chips' capabilities. Starting astatine the apical tier, the Ryzen 9 7950X has an tremendous betterment successful basal and boost frequencies, which makes Zen 4’s ratio amended than immoderate erstwhile Ryzen generation.

This has been imaginable successful portion done superior powerfulness efficiency, arsenic the Zen 4 nonfiction is mostly a Zen 3 refinement, but produced connected TSMC's 5 nm process node (from TSMC 7 nm). This ratio has allowed AMD to boost clockspeeds without breaking the powerfulness bank, with the 105W TDP 7700X seeing a 700MHz betterment for nary alteration successful TDP. Coupled with a 13% TDP improvement, and the Ryzen 7000 bid chips tin present immoderate important single-threaded show gains. And multi-threaded show is not near retired successful the cold, either; by expanding their apical TDP to 170W, AMD is capable to support the CPU cores connected their 12C and 16C parts astatine higher sustained turbo clocks, delivering overmuch amended show determination arsenic well.

Of people 1 of the cardinal arguments present is that much powerfulness equals much which is existent connected the portion of Ryzen 7000 series. Ryzen 7000’s TJ Max for its Precision Boost Overdrive exertion stands astatine 95°C, which means that the CPU volition usage each of the disposable thermal headroom to maximize performance.

Although this tin beryllium overridden erstwhile manually overclocking, this opens up the maximum TJ Max to 115°C. It’s cardinal to enactment that users volition request to usage much premium and assertive cooling types to compression each past driblet of show from Zen 4. The information that Ryzen 7000 runs blistery is accounted for by AMD done their plan choices and implementations. As such, they person opted not to bundle their ain CPU coolers with the retail packages, alternatively directing buyers to reasonably almighty third-party coolers.

New AM5 Socket: AM4 Coolers volition Support AM5 Too

AMD has besides transitioned to a caller chipset for Ryzen 7000, named AM5. Along with AM5 besides comes a caller socket, the LGA1718. Now what’s absorbing is AMD has specified that astir AM4 socketed coolers volition enactment the caller LGA1718 socket connected AM5; this is large for keeping with compatibility from the erstwhile generation.

This besides means that AM4 is present a happening of the past, though it does connection immoderate unthinkable close now, arsenic good arsenic enactment with the cheaper DDR4 too. AMD has of course switched to enactment for DDR5 memory, with JEDEC settings crossed each 4 CPUs acceptable astatine DDR5-5200; an betterment successful Intel’s 12th Gen Core bid enactment for DDR5-4800.

AMD has unveiled 4 caller chipsets, 2 Extreme variants named X670E and B650E, with 2 regular chipsets, aptly named X670 and B650, archetypal and simple. The apical tier X670E bid volition diagnostic some PCIe 5.0 lanes to the apical PEG slot, with enactment for PCIe 5.0 retention devices which are expected successful November 2022. As for its regular X670 chipset, PCIe 5.0 to the PEG slot is optional, not mandatory, similar connected X670E.

The B650 chipsets are designed to beryllium much affordable and, arsenic specified lone diagnostic PCIe 4.0 lanes to the PEG slot. They do, nevertheless diagnostic astatine slightest 1 PCIe 5.0 x4 retention slot. The B650E is reserved for those lower-end boards that privation to see PCIe 5.0 to the graphics card, though users looking to utilize PCIe 5.0 enactment should opt for,X670E; amended boards, amended controllers, and amended specifications.

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

As we’ve seen antecedently from the Ryzen 5000 series, AMD uses chiplet packaging, with 2 halfway analyzable dies (CCD) connected its apical SKU, with an I/O dice hosting each of the PCIe 5.0, the integrated representation controller (IMC), and caller for Ryzen 7000, 2 CU’s of AMD’s rDNA 2 integrated graphics. Some cardinal advantages of AMD’s caller 6 nm TSMC I/O dice means much transistors, amended ratio astatine the manufacturing stage, and yet astir importantly of all, from an ratio constituent of view, little wide powerfulness draw.

It’s clip to dive heavy into each of AMD’s caller improvements and changes for its Zen 4 microarchitecture. Over the pursuing pages we’ll, beryllium going implicit the following:
