AMD has announced the Ryzen 7000-series desktop processors along with the AM5 socket and 600-series motherboard chipsets, all set to release on September 27 starting at US$299.

Zoom on the Ryzen 7000 series processors
AMD General Manager Lisa Su said at the launch event that the Ryzen 9 7950X delivers 15% better performance than the previous generation Ryzen 9 5950X in popular games, thanks to improved performance at a single thread. For creators, Su said the Ryzen 9 7950X averages 40% better performance than the Ryzen 9 5950X.
Moving on to a comparison chart with current Intel processors, Su claimed that the Ryzen 9 7950X is “the fastest processor in the world.” She pointed out that it is faster across all gaming titles and offers 62% better compute performance at 47% better performance per watt.
With Intel’s 13th Gen processors set to debut later this year, the race is on for performance supremacy. AMD has announced that the Ryzen 7000 series will be able to reach a peak frequency of 5.7 GHz without overclocking, the highest in the industry. Intel’s Raptor Lake, on the other hand, is said to be capable of up to 6 GHz out of the box.
But clock frequency is only one variable in the performance equation. AMD claims that compared to Zen 3, Zen 4 brings on average a 13% increase in instructions per clock (IPC), which translates to a 29% performance boost on a single thread compared to the Ryzen series 5000. Onstage, AMD CTO Mike Papermaster attributed the improvement to a more refined front-end processor, particularly branch prediction, which accounted for 60% of the total IPC gain. Additionally, the OpCache has been increased by 1.5 times to increase the instruction hit rate.
AMD claims that the Ryzen 7000 series processors are not only faster, but also more energy efficient. With a 20% reduction in device capacity and other design improvements, Zen 4 delivers 62% less power at the same performance and 49% more performance at the same power compared to Zen 3.
The Zen 4 core is built using TSMC’s 5nm N5 node. According to AMD, the two companies worked together to tweak the CPU design to allow for higher frequencies, optimizing device scaling, capacity, and the metal stack to increase performance. Additionally, TSMC’s N5 node has reduced die area by 18% despite adding new features including AVX-512 support.
Support for Zen 4’s AVX-512 instructions is a first for AMD processors. AVX-512 instructions use a very wide 512-bit vector, which can be more efficient in specific tasks such as accelerated computing, deep learning, and cryptography. The decision to include support for the AVX-512 is the opposite of Intel, which first created the instruction set but decided to exclude it from its large desktop processors. 12th generation audience.
Consumer use cases for the AVX-512 are rare, but AMD promises 1.3x better performance in 32-bit precision floating-point inference operations. Additionally, Zen 4 supports VNNI neural network instruction extensions. And in desktop applications, AMD claims that Zen 4’s VNNI support running with int-8 data is 2.5x faster than Ryzen 5000 series processors, speeding up tasks like processing. natural language.
Looking to the future, AMD promises to release Ryzen 7000 series desktop processors with 3D V-Cache. Next-gen Zen 5 processors are also on track for 2024.
New AM5 socket, 600 series chipset and DDR5 memory
The Ryzen 7000 series CPUs use the new 1718-pin Land Grid Array (LGA) AM5 socket, which means people looking to upgrade will have to commit to a new motherboard. Along with purchasing a new card, users will also need to purchase a DDR5 memory package, as there is no backwards compatibility with DDR4.
Along with the new memory, AMD is also introducing EXPO memory profiles for one-click memory overclocking, similar to Intel’s XMP profiles. AMD claims EXPO can help speed up gaming performance by up to 11% while reducing latency to 63 nanoseconds. At launch, AMD expects more than 15 EXPO memory kits to hit the market at data rates up to 6400 MHz.
While the memory isn’t backwards compatible, AMD promises the socket will support AM4 coolers, so don’t throw those away just yet.
There are a lot of improvements to look forward to. The AM5 socket increases the power delivered by the socket to 230W and opens up support for future technologies, like PCIe 5 lanes.
The 600-series motherboard chipsets are divided into Enthusiast X-series and Consumer B-series, then divided into Enthusiast and Non-Enthusiast versions, as indicated by an “E” suffix.
Again, their differentiating factor lies in their number of connections. All X600 series cards offer PCIe 5 M.2 storage slots, while the X670 Extreme cards will also feature PCIe 5 lanes to graphics. The same hierarchy applies to the B-series cards. The B650E will have both PCIe 5 M.2 storage slots and a GPU slot, while the B650 cards will only have a PCIe 5 M storage slot .2.
Although rare now, AMD says PCIe 5 storage devices will hit shelves later this year, coinciding with the launch of its new processors.
The X600 series motherboards will be available on September 27. The B600 series motherboards will arrive in October.
What about competition from Intel?
Motherboards with the AM5 socket and 600 series chipset will start at US$125. Building on its commitment to support its long-term socket, AMD has committed to supporting the AM5 socket until at least 2025.
Topping the lineup is the Ryzen 9 7950X with 16 cores and 32 threads at US$699. As the highest performing chip in the lineup to date, it features a 5.7GHz boost clock and 80MB of cache. It’s followed by the $549 Ryzen 9 7900X with 12 cores and 24 threads, 76MB of cache, and the same 170W thermal design power (TDP).
The launch price of the Ryzen 9 7900 series processors is comparable to the launch price of its Ryzen 9 5900 series. That said, the Ryzen 5000 series processors are now on sale for $200 off to clear inventory for the next version. More importantly, however, the cost of the Ryzen 9 7900X is comparable to the 16-core, 24-thread Intel Core i9-12900K/KF. Although the Ryzen 9 7900X appears to have fewer cores, half of the Core i9-12900K cores are efficiency cores and do not support hyperthreading.
For the performance mainstream, AMD offers the 8-core/16-thread Ryzen 7 7700X for $399 and the 6-core/12-thread Ryzen 5 7600X for $299. These Ryzen 7 processors are priced just above the current retail price of the 12-core Intel Core i7-12700K and the 10-core Core i5-12600K.
The comparison gets a little interesting here because the Intel chips match the new Ryzen chips in terms of performance core count, but also come with additional efficiency cores. Considering its pricing, AMD seems confident that the design improvements will outperform its Intel rivals despite a core count disadvantage.
Unfortunately, the blue team’s true competitors won’t arrive until Intel launches its 13th-generation “Raptor Lake” desktop processors later this year. Raptor Lake is expected to be built using Intel’s Node 7, formerly known as 10nm Enhanced SuperFin. Like AMD Zen 4 processors, Raptor Lake is also expected to debut with PCIe 5 and DDR5 (both of which are already present on Intel’s 12th Gen ‘Alder Lake’ desktop processors) and is expected to feature up to 24 cores, including the new “Raptor Cove Performance Core Architecture (P-core). Intel has yet to specify an exact release date, but expect an uphill battle when it arrives.
