The Intel Core i9-7980XE and Core i9-7960X CPU Review Part 1: Workstation

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.
All of our benchmark results can also be found in our benchmark engine, Bench.
Corona 1.3: link
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: link
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.
LuxMark v3.1: Link
As a synthetic, LuxMark might come across as somewhat arbitrary as a renderer, given that it's mainly used to test GPUs, but it does offer both an OpenCL and a standard C++ mode. In this instance, aside from seeing the comparison in each coding mode for cores and IPC, we also get to see the difference in performance moving from a C++ based code-stack to an OpenCL one with a CPU as the main host.
POV-Ray 3.7.1b4: link
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: link
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.

Just curious mmrezaie, why do you say "unofficially"? ECC support is included on specs pages for X399 boards.frowertr - Tuesday, September 26, 2017 - link
Run Unbound on a Pi or other Linux VM and block all thise adverts at the DNS level for all the devices on your LAN. I havent seen a site add anywhere in years from my home.Notmyusualid - Thursday, September 28, 2017 - link
@frowertrInteresting - But that won't work for me - I'm a frequent traveller, and thus on different LANs all the time.
But what works for me, is PeerBlock, then iblocklist.com for the Ad-server & Malicious lists and others, add Microsoft and any other entity I don't want my packets broadcast to (my Antivirus alerts me when I need updates anyway - and thus I temporarily allow http through the firewall for that type of occasion).

This is why the "core wars" won't be a good thing for consumers. Focus on better single thread perf instead quantity.sonichedgehog360@yahoo.com - Monday, September 25, 2017 - link
On the contrary, single-threaded performance is largely a dead end until we hit quantum computing due to instability inherent to extremely high clock speeds. The core wars is exactly what we need to incentivize developers to improve multi-core scaling and performance: it represents the future of computing.extide - Monday, September 25, 2017 - link
Some things just can't be split up into multiple threads -- it's not a developer skill level or laziness issue, it's just the way it is. Single threaded speed will always be important.PixyMisa - Monday, September 25, 2017 - link
Maybe, but it's still a dead end. It's not going to improve much, ever.HStewart - Monday, September 25, 2017 - link
As a developer for 30 years this is absolutely correct - especially with the user interface logic which includes graphics. Until technology is a truly able to multi-thread the display logic and display hardware - it very important to have single thread performance. I would think this is critically important for games since they deal a lot with screen. Intel has also done something very wise and I believe they realize this important - by allowing some cores to go faster than others. Multi-core is basically hardware assisted multi-threaded applications which is very dependent on application design - most of time threads are used for background tasks. Another critical error is database logic - unless the database core logic is designed to be multithread, you will need single point of entry and in some cases - they database must be on screen thread. Of course with advancement is possible hardware to handle threading and such, it might be possible to over come these limitations. But in NO WAY this is laziness of developer - keep in mind a lot of software has years of development and to completely rewrite the technology is a major and costly effort.lilmoe - Monday, September 25, 2017 - link
There are lots of instances where I'd need summation and other complex algorithm results from millions of records in certain tables. If I'm going the traditional sql route, it would take ages for the computation to return the desired values. I instead divide the load one multiple threads to get a smaller set in which I would perform some cleanup and final arithmetic. Lots of extra work? Yup. More ram per transaction total? Oh yea. Faster? Yes, dramatically faster.WPF was the first attempt by Microsoft to distribute UI load across multiple cores in addition to the gpu, it was so slow in its early days due to lots out inefficiencies and premature multi-core hardware. It's alot better now, but much more work than WinForms as you'd guess. UWP UI is also completely multithreaded.
Android is inching closer to completely have it's UI multithreaded and separate from the main worker thread. We're getting there.
Both you and sonich are correct, but it's also a fact that developers are taking their sweet time to get familiar with and/or use these technologies. Some don't want to that route simply because of technology bias and lock-in.

"Both you and sonich are correct, but it's also a fact that developers are taking their sweet time to get familiar with and/or use these technologies. Some don't want to that route simply because of technology bias and lock-in."That is not exactly what I was saying - it completely understandable to use threads to handle calculation - but I am saying that the designed of hardware with a single screen element makes it hard for true multi-threading. Often the critical sections must be lock - especially in a multi-processor system.
The best use of multi-threading and mult-cpu systems is actually in 3D rendering, this is where multiple threads can be use to distribute the load. In been a while since I work with Lightwave 3D and Vue, but in those days I would create a render farm - one of reason, I purchase a Dual Xeon 5160 ten years ago. But now a days processors like these processors here could do the work or 10 or normal machines on my farm ( Xeon was significantly more power then the P4's - pretty much could do the work of 4 or more P4's back then )
