The AMD Ryzen 5 1600X vs Core i5 Review: Twelve Threads vs Four at $250

Rendering tests are a long-time favorite of reviewers and benchmarkers, as the code used by rendering packages is usually highly optimized to squeeze every little bit of performance out. Sometimes rendering programs end up being heavily memory dependent as well - when you have that many threads flying about with a ton of data, having low latency memory can be key to everything. Here we take a few of the usual rendering packages under Windows 10, as well as a few new interesting benchmarks.
Corona 1.3
Corona is a standalone package designed to assist software like 3ds Max and Maya with photorealism via ray tracing. It's simple - shoot rays, get pixels. OK, it's more complicated than that, but the benchmark renders a fixed scene six times and offers results in terms of time and rays per second. The official benchmark tables list user submitted results in terms of time, however I feel rays per second is a better metric (in general, scores where higher is better seem to be easier to explain anyway). Corona likes to pile on the threads, so the results end up being very staggered based on thread count.
Blender 2.78
For a render that has been around for what seems like ages, Blender is still a highly popular tool. We managed to wrap up a standard workload into the February 5 nightly build of Blender and measure the time it takes to render the first frame of the scene. Being one of the bigger open source tools out there, it means both AMD and Intel work actively to help improve the codebase, for better or for worse on their own/each other's microarchitecture.
POV-Ray 3.7.1
Another regular benchmark in most suites, POV-Ray is another ray-tracer but has been around for many years. It just so happens that during the run up to AMD's Ryzen launch, the code base started to get active again with developers making changes to the code and pushing out updates. Our version and benchmarking started just before that was happening, but given time we will see where the POV-Ray code ends up and adjust in due course.
Cinebench R15
The latest version of CineBench has also become one of those 'used everywhere' benchmarks, particularly as an indicator of single thread performance. High IPC and high frequency gives performance in ST, whereas having good scaling and many cores is where the MT test wins out.

That wasn't my point, readers shouldn't go elsewhere to compare with CPUs that are excluded due to bias.Meteor2 - Wednesday, April 12, 2017 - link
What relevance has a $340 CPU got to a $250 CPU review?vladx - Wednesday, April 12, 2017 - link
I'd say a ton more than the $499 Ryzen 7 1800x which didn't get excluded.psychobriggsy - Wednesday, April 12, 2017 - link
Yes, it's in the same product line, so people can see how it compares.Which seems to be roughly around 80% of the 1800X, for around half the price.

And 7700k is more relevant for gaming which was the subject at hand so there you go.Meteor2 - Wednesday, April 12, 2017 - link
You didn't answer my question...vladx - Wednesday, April 12, 2017 - link
I just did, 7700k is more relevant than a 1800X in gaming benchmarks and as the competition it should've been included if a $499 CPU from AMD is included.psychobriggsy - Wednesday, April 12, 2017 - link
7700K is at a different price point, it rightly was compared in the Ryzen 7 reviews.Regardless, it would lose in the multithreaded benchmarks still, whilst having a small extra advantage in the gaming results.

Ryzen 1800X is even more expensive than 7700k and yet got included in the gaming benchmarking, ironically considering 7700k is much more relevant for gaming.Sorry, but the bias and double standards are obvious in the article.
