8-core AMD Ryzen 7 CPU good news for CAD users who render

If you use CAD alongside a physically-based renderer like KeyShot, V-Ray or PhotoView 360, read on, as this could seriously change the way you approach your next workstation purchase.

AMD has just announced its first 8-core Ryzen 7 desktop CPUs, which promises to slash render times without putting a serious dent in your hardware budget.

AMD claims that its flagship model, the Ryzen 7 1800X, is the world’s highest performing 8-core desktop processor. It backs this up with benchmarks that show the CPU beating the Intel Core i7-6900K by 9 per cent in the multi-threaded Cinebench rendering test, and delivering parity in the single threaded test, at out of the box frequencies.
This is impressive, in itself, but the biggest news is that the Ryzen 7 1800X is priced at $499 – less than half that of the Core i7-6900K, listed at the time of writing at $1,089 on Intel.com.

It’s no secret that CAD loves GHz and CPU renderers love cores. However, most CAD users don’t go above four cores because of the premium that Intel attaches to high frequency, multi-core CPUs.

Now, with AMD offering a competitive eight core CPU for only 30% more than the quad core Intel Core i7-6700K ($339 at time of writing), this could change buying habits, resulting in significantly reduced render times for those who come on board.


While we don’t imagine the Tier One workstation vendors – Dell, HP, Lenovo and Fujitsu – will adopt Ryzen 7, we do expect specialist, more agile workstation manufacturers like Armari, Scan and Workstation Specialists to take a serious look at the technology.

It will also be interesting to see how Intel reacts. If Ryzen gains traction it could see Intel drop the price of its premium desktop CPUs, which is good news for everyone.

AMD has three Ryzen 7 models in total. All have 8 cores and 16 threads and support simultaneous multi-threading, AMD’s equivalent of Intel HyperThreading, which is supported by most physically-based renderers.

• Ryzen 7 1800X (3.6 GHz base, 4.0 GHz turbo) – $499
• Ryzen 7 1700X (3.4 GHz base, 3.8 GHz turbo) – $399
• Ryzen 7 1700 (3.0 GHz base, 3.7 GHz turbo) – $329
