CPU Performance: Synthetic Tests
As with most benchmark suites, there are tests that don’t necessarily fit into most categories because their role is just to find the peak throughput in very particular coding scenarios. For this we rely on some of the industry standard tests, like Geekbench and Cinebench.
GeekBench4: Synthetics
A common tool for cross-platform testing between mobile, PC, and Mac, GeekBench 4 is an ultimate exercise in synthetic testing across a range of algorithms looking for peak throughput. Tests include encryption, compression, fast Fourier transform, memory operations, n-body physics, matrix operations, histogram manipulation, and HTML parsing.
I’m including this test due to popular demand, although the results do come across as overly synthetic, and a lot of users often put a lot of weight behind the test due to the fact that it is compiled across different platforms (although with different compilers).
We record the main subtest scores (Crypto, Integer, Floating Point, Memory) in our benchmark database, but for the review we post the overall single and multi-threaded results.
LinX: LINPACK
The main tool for ordering the TOP500 computer list involves running a variant of an accelerated matrix multiply algorithm typically found from the LINPACK suite. Here we use a tool called LinX to do the same thing on our CPUs. We scale our test based on the number of cores present in order to not run out of scaling but still keeping the test time consistent.
This is another of our new tests for 2020. Data will be added as we start regression testing older CPUs.
Cinebench R20
The Cinebench line of tests is very well known among technology enthusiasts, with the software implementing a variant of the popular Cinema4D engine to render through the CPU a complex scene. The latest version of Cinebench comes with a number of upgrades, including support for >64 threads, as well as offering a much longer test in order to stop the big server systems completing it in seconds. Not soon after R20 was launched, we ended up with 256 thread servers that completed the test in about two seconds. While we wait for the next version of Cinebench, we run the test on our systems in single thread and multithread modes, running for a minimum of 10 minutes each.

The ability to edit (or ^Z) would be most welcome, trust me.eastcoast_pete - Wednesday, May 20, 2020 - link
Isn't that Skylake running a bit dry by now? But, seriously, Intel really risks losing a lot of market share in future years by selling these "classics" at high prices, and that is if one can get one in the first place.Curious: how many commercial customers buy Intel desktops just because they have iGPUs, but want more CPU oomph than the 3200G has? Is that why Intel still dominates the OEM desktop market?

Intel dominates the OEM market through intimidation and threats of retribution... They were literally convicted of bribing OEMs to NOT use AMD CPUs all throughout the 2000s in several courts around the world. The trials uncovered emails between Intel executives that stated, and I quote, "Dell is the best friend money can buy".... The proof is in the fact that currently, the Ryzen 4000 mobile CPUs are the best mobile chips offered right now, but Dell only puts them in the low end laptops. Why? Because Intel is probably giving huge financial incentives to bar AMD from premium designs to perpetuate the myth that AMD isn't a premium brandRetycint - Wednesday, May 20, 2020 - link
Do keep in mind that these are baseless speculations, based on something that happened 2 decades ago. Both Intel and AMD have changed since then (new engineering team, new management etc) and there has been no evidence of Intel providing incentives to cripple AMD systems. Go take your conspiracy elsewhere.And before you inevitably accuse me of being an Intel shill, this isn't about Intel or AMD, it's about facts to support your claim, of which there have been none

Baseless speculation? Financial horsepower, MDF and meet the comp funds are current and no secret.Why do you think there are no Ryzen 4000 laptops with GPU above a 2060?

Not entirely baseless, as they made two distinct claims. I've been a party to how Intel's "Marketing Development Funds" work - and work it does, at all levels from OEM to reseller to retailer. These days they don't explicitly punish anyone for not buying AMD - they simply tie rebates that will improve the profit margins on a product to specific quantities of those products being sold. It's "nobody's fault" if those quantities happen to make the sale of an AMD product by a given retailer or reseller distinctly unlikely.As for incentivizing bad *builds* of AMD systems, though, I'm not so sure. Intel clearly do a lot of work building reference platforms, and the economics of doing integration testing for a new vendor is not trivial. Honestly though, it's hard to tell how we *would* know if this were going on, because it would absolutely be made to look innocent - just like last time.

"literally convicted of bribing"1) No. That's not what "literally" means.
2) No. No one was even *charged* with a crime, much less convicted.
3) No. It wasn't about bribery.
The reason Athlon 64s weren't ubiquitous way back when is the same reason the 4000 APUs aren't today - there aren't enough to go around.
If your post were to be rephrased without hyperbole, baseless accusations, and whataboutism unrelated to the topic of this article, it would read something like this:
"6 months after AMD's announcement of Renoir, the number of 4000 APUs sold for desktops is literally zero (see how that works?) because TSMC is still slammed."

Your ignorance is amusingIt is technically a bribery

First 3 points: accurate, if not entirely on-topic. Nobody was charged with a crime, but Intel sure were fined a lot for collusion.Which gets to the 4th point: again, accurate, but not entirely relevant. AMD were definitely not able to match Intel for manufacturing, which is why they couldn't have beaten Intel out of the market entirely, but that was barely related to why they weren't getting into Dell systems. See the aforementioned proven-and-fined-for collusion.

Or because premium designs take longer when the new chip isn't just another respin of the same thing, and AMD hadn't produced a viable high-end notebook chip in well over a decade so it made sense to wait and see if Ryzen 4000 was any good rather than designing in advance?
