AMD Announces Ryzen 5 Lineup: Hex-Core from $219, Available April 11th
See the original posting on Anandtech
As part of our initial Ryzen 7 review, AMD also teased the presence of two more elements to the Ryzen lineup, specifically Ryzen 5 and Ryzen 3, both aiming at a lower cost market and allowing AMD to sell some of the silicon that didn’t quite make it to the Ryzen 7 lineup. Today is the official announcement for Ryzen 5, featuring four processors in hex-core and quad-core formats, all with Simultaneous Multi-Threading (SMT) and all using the same AM4 platform as Ryzen 5.
Whereas Ryzen 7 was AMD’s main attack on high-performance x86 and a shot across the bow against Intel’s high-end desktop platform, Ryzen 5 is targeted more at mainstream users. The goal here is that where Intel has four cores with no hyperthreading, AMD can provide six cores with SMT, effectively offering three times as many threads for the same price and potentially smashing any multithreaded workload.
Without further ado, here is where the Ryzen families stand:
|AMD Ryzen 7 SKUs|
|Ryzen 7 1800X||8/16||3.6/4.0||+100||16 MB||95 W||$499||–|
|Ryzen 7 1700X||8/16||3.4/3.8||+100||16 MB||95 W||$399||–|
|Ryzen 7 1700||8/16||3.0/3.7||+50||16 MB||65 W||$329||Spire
|AMD Ryzen 5 SKUs|
|Ryzen 5 1600X||6/12||3.6/4.0||+100||16 MB||95 W||$249||–|
|Ryzen 5 1600||6/12||3.2/3.6||+100||16 MB||65 W||$219||Spire|
|Ryzen 5 1500X||4/8||3.5/3.7||+200||16 MB||65 W||$189||Spire|
|Ryzen 5 1400||4/8||3.2/3.4||+50||8 MB||65 W||$169||Stealth|
Traditionally we are used to a part with fewer cores having a higher clock frequency, however perhaps due to the voltage scaling of the design, we see a matched Ryzen 5 1600X in frequency to the Ryzen 7 1800X, but the rest of the Ryzen 5 family are offered at a lower TDP instead.
All the Ryzen 5 parts are unlocked, similar to the Ryzen 7 parts, and all four exhibit some movement in XFR mode, with the 1500X offering +200 MHz depending on the cooler used. AMD is going to offer some of these SKUs with their redesigned Wraith coolers:
It is worth noting that the Wraith Spire for Ryzen 5 will not have RGB lighting, whereas the Wraith Spire for Ryzen 7 does use an RGB ring. OEMs will be able to use the higher-end Wraith Max stock cooler for their pre-built systems. AMD stated that at present, there are no plans to bring the Wraith coolers to retail as individual units, however they will keep track of how many users want them as individual items and regularly approach the issue internally.
To clarify some initial confusion, AMD has given me official TDP support numbers for the coolers. The entry level Wraith Stealth is 65W, the Wraith Spire is 65W for high-ambient conditions (AMD states this might be considered an ’80W’ design in low-ambient), and the Wraith Max is 95W for OEM builds using Ryzen 7 95W parts.
All the Ryzen 5 parts will support DDR4 ECC and non-ECC memory, and the memory support is the same as Ryzen 7, and will depend on how many modules and the types of modules being used. Recently companies like ADATA announced official support for AM4, as some users have found that there were memory growing pains when Ryzen 7 was launched.
Platform support for Ryzen 5, relating to PCIe lanes and chipset configurations, is identical to Ryzen 7. Each CPU offers sixteen PCIe 3.0 lanes for graphics, along with four lanes for a chipset and four lanes for storage. Chipsets can then offer up to eight PCIe 2.0 lanes which can be bifurcated up to x4 (AMD GPUs can use chipset lanes for graphics as well, however at reduced bandwidth and additional latency).
The high-end Ryzen 5 1600X, at $249, is a shoe-in to compete against Intel’s i5-7600K at $242. Intel’s CPU is based on the Kaby Lake microarchitecture, and we’ve already shown in the Ryzen 7 review that by comparison Ryzen is more circa Broadwell, which is two generations behind. AMD won’t win much when it comes to single-threaded tests here, but the multi-threaded situation is where AMD shines.
|Comparison: Ryzen 5 1600X vs Core i5-7600K|
Ryzen 5 1600X
|6 / 12||Cores/Threads||4 / 4|
|3.6 / 4.0 GHz||Base/Turbo||3.8 / 4.2 GHz|
|16||PCIe 3.0 Lanes||16|
|16 MB||L3 Cache||6 MB|
|95 W||TDP||91 W|
Here we have twelve threads against four, at a 95W TDP compared to a 91W TDP (the 1600 is 65W, which looks better on paper). It is expected that for situations where a compute workload can scale across cores and threads that the AMD chip will wipe the floor with the competition. For more generic office workloads, it will interesting to see where the marks fall.
On the quad-core parts, there are several competitive points to choose from. The AMD Ryzen 5 1500X, at $189, sits near Intel’s Core i5-7500 at $192. This would be a shootout of a base quad-core versus a quad-core with hyperthreading.
