AMD Ryzen 7 Series Processor Reviews Go Live, Zen Looks Strong Vs Intel (hothardware.com)
MojoKid writes: AMD has finally lifted the veil on independent reviews of its new Ryzen series of desktop processors that bring the company's CPU architecture back more on competitive footing versus its rival, Intel's Core series. The initial family of Ryzen processors consists of three 8-core chips, the Ryzen 7 1800X at 3.6GHz with boost to 4.1GHz, the Ryzen 7 1700X at 3.4Ghz with boost to 3.8GHz, and the Ryzen 7 1700 at 3GHz with boost to 3.7GHz. Each has support for 2 threads per core, for a total of 16 threads with 16MB of L3 cache on-board, 512K of L2 and TDPs that range from 65 watts for the Ryzen 7 1700 at the low-end, on up to 95 watts for the 1700X and 1800X. In comparison to AMD's long-standing A-series APUs and FX-series processors, the new architecture is significantly more efficient and performant than any of AMD's previous desktop processor offerings. AMD designed the Zen microarchitecture at the heart of Ryzen with performance, throughput, and efficiency in mind. Initially, AMD had reported a 40% target for IPC (instructions per clock) improvement with Zen but actually realized about a 52% lift in overall performance. In the general compute workloads, rendering, and clock-for-clock comparisons, the Ryzen 7 1800X either outperformed or gives Intel's much more expensive Core i7-6900K a run for its money. The lower clock speeds of the Ryzen 7 1700X and 1700 obviously resulted in performance a notch behind the flagship 1800X, but those processors also performed quite well. Ryzen was especially strong in heavily threaded workloads like 3D rendering and Ray Tracing, but even in less strenuous tests like PCMark, the Ryzen 7 series competed favorably. It's not all good news, though. With some older code, audio encoding, lower-res gaming, and platform level tests, Ryzen trailed Intel -- sometimes by a wide margin. There's obviously still optimization work that needs to be done -- from both AMD and software developers.
some older games...and it still performed quite strong without optimization...and it's half the price of the $1000+ intel processor that it trailed by 20% but feel free to pay the extra $500 for 20% more performance for some older games.
Looking more like crappy game code than crappy processor. Reviews show Ryzen doing particularly well on high quality settings. Regardless of gaming, which really is all about the GPU especially with Vulkan games coming down the pipe, Ryzen by all appearances is a kickass workstation chip at a gimme price. Because of Ryzen, I expect to pay less for my next desktop than my next phone.
When all you have is a hammer, every problem starts to look like a thumb.
I have a feeling feeding a multi GPU rig will show some of its muscles. STH has some nice benchmarks showing it holding its own against a lot of Xeons.
After a while the virtualization code I was working with just stopped being maintained upstream for AMD because the value proposition was just so ludicrously bad vs. Intel and nobody was using them.
Has AMD, perchance, contributed code to KVM or Xen to get a running start or are we going to be waiting until after Intel's next chip rev. before Zen stands a chance again in this arena (at which point, it's already lost its advantage)?
My God, it's Full of Source!

In general, the reviews are negative. We knew Ryzen would be behind in single-threaded performance, and it is. But it's also behind in multi-threaded performance in a lot of benchmarks for some reason. It beats out Intel's offerings in certain workloads (primarily video encoding), but it gets its ass handed to it in games.
On FP-heavy workloads it's toe-to-toe with Intel processors costing twice as much. On integer-heavy workloads Intel still has the better technology but on price/performance it's correctly priced between the i7-7700k and Intel's HEDT offering. On memory-heavy workloads the dual channel is no match for Intel's quad channel but the price/performance is still okay as far as I've seen.
Where it does fall short is single/few-threaded games if you game at low resolution/high frequency but since hardly any gamer would spend $1000 on an 8C Intel processor it's no surprise games don't really take any advantage of the last four cores, even hyper-threading 4C/8T doesn't do much for gaming. But if you move to 1440p the difference is less, at 4K you're GPU limited anyway.
Basically if you'll only be using it for gaming and have a Sandy Bridge or newer just save your money and use it for a 1080 Ti or Vega. I find the reviews are trying really trying to make games CPU bound when they're mostly not, at least the way I prefer to play them. Maybe the FPS addicts with 144Hz monitors see it differently, I prefer higher quality as long as frame rates are reasonably smooth.

> $500 R7 1800X vs $340 i7 7700k.
The 1800X is like 8 cores to the 7700K's 4 cores. The 7700K, having half the cores, will presumably do better on single threaded tasks, such as the benchmarks in question. Future code, especially that which makes requests to the GPU in a multithreaded fashion, will perform better with more damned cores. For single threaded (or basically that), the 7700K also blows away Intel's 6950X, their top desktop CPU offering with 10 cores.
A better comparison per price point would be the 1700X or 1700 to the 7700K. Again, you find that the 8 core chip blows away the 4 core chip on multiprocessing, with less amazing results from a single thread.
There's a ton of applications that scale well with cores, and games will begin to do so more in the future. There will always be tasks that can't be parallelized, but the question is, when do they matter versus the ones that can? The question of cores versus speed per dollar is about as old as CPUs, and the answer is always "what is your use case".
Don't forget Vulkan, which effectively puts the CPU in the back seat. And there are lots of great Ryzen reviews out there, in contrast to the Intel dicksuck site you picked.
1. Links to wccftech (the 4chan of tech sites)
2. Uses the word "dicksuck"
3. A poor CPU is still a poor CPU after Vulkan
And I say that as someone planning to buy a Ryzen.. is it perfect? No. But it's close enough that AMD deserves a sale so Intel doesn't get to monopolize the high end again. Just deciding on whether I'll hold out for Vega or not...

Rendering and video encoding is not an end-user application
Watch for "no true Scotsman" fallacies. How exactly do you define "an end-user application"? One focused on viewing works of authorship made by others rather than creating works?
The "bad" review? Was from hothardware....you ever went to that site without adblock? Last time I did the entire page was NOTHING but Intel ads.
From what I've seen there is 4 sites you should never listen to, hothardware, Ars Technica, and the worst are Tom's Hardware (where their "expert" told a person asking what CPU to buy for GAMING that he should buy a Pentium dual core over a lower priced AMD X6 even though he admitted that most games the person wanted to play required a quad) and Anandtech who went so far as to drop several new triple A titles from their benchmark that so happened to play better on AMD hardware and replaced them with older titles that were expressly built with Nvidia Gameworks (which has been shown to have "cripple AMD" code baked in)...you wanna guess who their biggest advertiser is?
Its sad that I have to even say this but you really have to do some digging before you can actually take any "news" as credible as we have had so many cozy deals with advertisers and companies affiliated with those they are reviewing that a good chunk of what you see and hear these days is just corporate propaganda or FUD.
ACs don't waste your time replying, your posts are never seen by me.
Too bad Ryzen only supports Windows 10
Source? My sources say GNU/Linux runs on it.

Toms Hardware is excellent, from my experience, for their hardware reviews. I've been building my own systems for a long time now and have used their reviews as primary source for selecting hardware components and have never had a problem with their findings. As for their "forum experts", I've had no experience with them. Saying that a whole site is horrible based on one bad experience is a tad on the extreme side, though.
From a PC gaming perspective, until recently, very few games have taken full advantage of multi-core processors. Even if a game uses multi-core, they tend to be poorly optimized such that the load is not spread evenly across all cores. Your still better off getting the fastest CPU that you can buy even if it means getting a quad-core vs an octa-core.
single-thread performance is king for games
It was, some time last decade. Apparently you have not heard about Vulkan. Applications are going that way too, and, well, everything.
