The top CPU is almost 4 times faster than my CPU (i5 6600K). Is it just down to the GHz and number of cores? Besides those two elements, what makes this processor so much faster?

Pipeline depth, cache sizes and types, number of execution units, memory links and bandwidth and on and on. Absent are measurements for enterprise CPUs like the Xeon Platinum 8180M (street price about $13,000 USD) which trounces the fastest offering from AMD before even getting out of bed. [0] Note 0: For multi-threaded uses. For single-threaded use-cases, the Xeon Gold 6144 has the potential to be faster: - Gold 614…

- Are you really comparing a $1000 CPU to a $13,000 CPU?

- Threadripper is not Enterprise. Are you not aware of Epyc?

I would like to point out that even in some benchmarks AMD is not on the top, it doesn't mean it's no the best buy product. There are other factors like heat production and power consumption, which Ryzen has even 3 times lower than equivalent Intel CPU.

Truly brilliant for sure. Reminds me of Anders Hejlsberg who designed Typescript, Delphi, and C#. Or Linus Torvalds with Linux, and just to prove he wasn't a one hit wonder designing Git. I've concluded that what people fail to grasp about technology is that Einstein types still exist. There are rare engineers worth hundreds of times more than average, only this time they're well paid by their corporate masters. More…

Let's not get ahead of ourselves there on git. _Have you tried using submodules?_ :P

I don't think submodules were designed by Linus.

I get that, but given that GPUs currently can't use (for physical connector) / don't benefit from more than 16 lanes. Unless you are using multiple GPUs or another PCI device, you would not benefit from more than 16 lanes. How does that hold GPU manufacturers back?

> Unless you are using multiple GPUs or another PCI device You mean like having a GPU and one or more PCIE NVMe storage-devices?

No, as in 4 GPUS and/or one or more PCIE NVMe storage devices or PCI based comms cards such as infiniband cards.

Git was helped by Github, and being a requirement for Linux development. Otherwise I might be enjoying Mercurial nowadays.

I AM enjoying mercurial these days. It's a joy to work with. For most git tasks I can just clone it using hg-git, and work with it just like that, and push it back to github for a PR/CI.

What makes PassMark a representative CPU benchmark? These one-company CPU benchmarks tend to be quite problematic (cf. GeekBench). SPEC just came out with CPU2017. In SPEC there's at least a bunch of peer review, transparency and attention from academics. Here are Anandtech's AMD vs Intel CPU2006 numbers: http://www.anandtech.com/show/11544/intel-skylake-ep-vs-amd-... http://www.anandtech.com/show/11544/intel-skylake…

> What makes PassMark a representative CPU benchmark?

Sadly nothing. PassMark is infamous for being not representative, and you can easily check that by looking at the position of the FX processors, which are rated way too high.

I run a pc hardware builder with a recommender function at its core, which means that the real core is the meta benchmark powering the recommender. It works by taking professional reviews of real life workloads, and I think it is a lot more realistic, though absolute ordering is of course not that easy. I recently made the benchmark results visible, there is one for games: https://www.pc-kombo.com/benchmark/games/cpu and one for applications: https://www.pc-kombo.com/benchmark/apps/cpu . Threadripper is in there and the big model leads the app benchmark, but I still need to add more benchmarks with the threadripper processors to make the result more certain.

At the beginning I even started with the passmark results, but had to move to better data when user complained the results were not good. They were right.

Single core performance on the i9 is still going to be significantly higher though, so it depends on your use case. Testing I've seen so far has had the i9 getting about 20% higher framerates in games, for example.

Epyc has another stepping than Ryzen and, as far as I know, nobody could reproduce the "kill-ryzen" SEGFAULT on Epyc or Threadripper.

I sure hope so, but given the epic fail of Ryzen, I'm going to wait for others to beta test it for me, and/or for some sort of explanation and fix from AMD.

Well then you likely won't get the information you need as quickly as you need it.

Buy one, test it in your environment, file bug reports if you come across any. You don't need to replace your entire fleet in one go; Plan a phased rollout, starting with one workstation running the most aggressive of your workloads.

This. I've been trying to put together a small home lab xeon e3 system that can theoretically support nvme+gpu+infiniband. It's tough.

Typically you get something like 3 full length PCIe slotson a xeon e3 board (c236 chipset). BUT they can't all run full speed at 16x (16/16/16). You have to then choose between 16/8/8 and 16/16/0 due to the lack of PCI lanes.

From what I can tell he's disappointed that AMD don't offer a $13,000 CPU that competes with Intel.

Epyc falls short of the Xeon Platinum 8180 [0]
