Anyways the 1700x looks like a real steal, but I'm also pretty excited about the "mainstream enthusiast" zone. The 1400x and 1200x could be really great alternatives to the standard 7500 or 7600K that pretty much everybody slaps in their gaming pc. About the same performance, save $50, what's not to like? The 7700K is going to stay at the top of all gaming benchmarks though, so people who like to spend $350 for benchmark performance will stick with intel.

We just tested a 1700, it hit 4.0GHz stable in everything, but ONLY in the Crosshair mainboard, the lower-end boards it was hovering around 3.80GHz as the VRM’s were cooking with extra voltage. It however was maxing around 4050MHz, so I’d say 1700 can do 3.9-4.1GHz, of course the 1800X will probably do 4.1-4.3 as no doubt better binned, but if your clocking the motherboard has a big impact on the overclock and so far Asus Crosshair and Asrock Taichi seem the best two.

The record run shows a group of overclockers putting an AMD Ryzen 7 1800X chip through the test in Cinebench R15. The chip was cooled with LN2 and voltage was bumped to an outrageous 1.875V. This allowed the overclockers to push this chip to 5.2 GHz across all 8 cores using LN2 cooling which kept the chip operating at a cool -200c. This is absolutely amazing for a chip that is yet to be released for consumers.

At these speeds, the chip was able to score 2449 Cinebench points in the multi-threaded tests, breaking the previous world record of 2410 Cinebench points on an 8 core processor. The screenshot for this run wasn’t saved by anyone but another YouTuber managed to grab a few shots of what he was able to. The video can be seen below:

"Overclock is no problem at all. Though we can not say a certain frequency due to NDA, I can say that it is impressive. Overclockers will be happy."

"I have friends from AMD Engineering department due to my experience in the hardware industry. Zen 2 or Zen B will be even more competitive. So we can say that Intel shall brood on the future"

"With our overclocked 1800x sample,under Noctua cooler given by AMD, we have passed beyond the stock single thread performance of 7700k, in a specific bench, and the temps were great. We had no concern about temps during our run which passes the ST performance of 7700k."

"In some benchmarks AMD(!). It seems ironical yes but AMD is presenting a CPU performance that Intel can not keep up with even with their 10 core 6950x!"

"Breaking NDA won't be a problem since the scores are beyond fantastic. But we will stick with the tradition."

"With one click I can reach great OC's. So I won't really bother with the manual OC no more."

"Single thread score will be so great. According to this performance we can say that 7700K will be history, even for gaming, from now on" he said.

"Intel shall shake themself. Because Ryzen will be a great choice for Overclock enthusiast."

It says something that AMD's press team out in Turkey gave them a Noctua cooler instead of one of the new OEM ones.

Don't know really, but 5Ghz Kaby is plenty strong at gaming and not an unrealistic clock at all, unless you totally lose the silicon lottery.
Highly threaded engines hopefully love Zen, though. The multicore performance seems strong, we do know that.

Some food for thought which I posted in the memory thread.

First off we had some rumours about weak IMC due to supposedly low speed. This was followed by a rumour that actually Zen had insane efficiency way above Intel and as such lower speeds actually had same performance as higher on Intel.

This is a Zen getting 33.99GB/s out of 2133Mhz memory, which has a theoretical maximum bandwidth of 34.128GB/s... meaning, epic efficiency.

For comparison you have

http://ranker.sisoftware.net/show_run.php?q=c2ffcdffd9b8d9e4dcefdae3d5e7c1b38ebe98fd98a595b3c0fdcd&l=en

Broadwell-e with 3200Mhz memory achieving 74.97GB/s with max theoretical of 102.4GB/s, so around 75% efficiency.

http://ranker.sisoftware.net/show_run.php?q=c2ffcdffd9b8d9e4d3ebd3ead3e6c0b28fbf99fc99a494b2c1fccc&l=en

Skylake with similar (lower latency though) memory achieving 26.52GB/s at 2133Mhz, with obviously max theoretical of 34.128GB/s. A little over 75% efficiency. Another way to look at the results, if true, is that Zen has 28% higher bandwidth at the same memory speed.

If that scales at the same rate then 2666Mhz on Zen would give the same bandwidth that Skylake(and thus Kaby) would at 3400Mhz.

Along with those rumours was a mention that Zen was currently locked at 1t, we also have Asus managing to get higher memory speed. I wonder if Asus unlocked some settings that aren't supposed to be unlocked yet and in doing so managed to lower timings to up memory speeds, but sacrificing efficiency.

Basically I'm just trying to say, heads up, new platform, don't assume 2666Mhz is even bad, OR that 3200Mhz(at potentially much lower timings) is automatically better than 2666Mhz.

Posted this before, but another thing to bear in mind, Haswell tanked in bandwidth efficiency after 2400mhz. We absolutely do not know that super fast memory speeds will bring ANY better performance yet. I mean Sisoft doesn't usually get faked afaik, and the result fits with some rumour 1-2 weeks back, it would also explain most issues of getting higher memory speeds.

I would say, don't jump on a £250 board because someone is telling you 3200Mhz needs a £250 board, because we don't even know if 3200Mhz is faster, besides the fact that I fully expect lots of cheaper boards to be updated and tweaked to achieve ballpark similar clock speeds at some point anyway.

Its quite possible faster memory does little to nothing even in memory sensitive work loads for Zen. Thats not worth spending ~$100 more for.

So is it true that only the 8 core ryzens are coming out?

buglord posted:

How successful is unlocking cores? I've read about people doing this, but I also hear that most of the time the cores are faulty or something that can cause crashing? Is any of that true?

Either way, would be cool to see~

So it looks like Intel chips are still going to be better for gaming for now. Oh well, an i7-7700K it is then for my next build.

It's honestly what I expected, but not what I hoped for. It's a chip that's great for creators or anyone who uses their computer for more than one thing, but on the other hand it's not a great CPU for the Facebook-and-L33T-G4MEZZZZZZZZZZZ market lumpenproletariat.

Uhhh...

Why are his results so different?

I really can't tell you that for any degree of certainty. I do run the majority of my benchmarks in game rather than using any built in benchmarks like GTA 5. The only exception is Rainbow Six Siege which is rather difficult to recreate the same scene repeatedly. Also may come down to settings. For simplicity I just hit the ultra preset and left it at that. No other changes were made to the settings in these runs.

buglord posted:

Man thats a huge shame. At the very least, I was expecting some competition (or at least a compelling alternative) at this front. But unless you wanna throw AMD some sympathy dollars, this looks pretty sad. Is it too early to say their mid and low end offerings in the future are going to underperform just as badly? Or is that going to be solely based on their asking price?

Voyager I posted:

How long is it going to be before the 4 core models that are better suited to modest gaming machines are out? Even assuming they manage to sort themselves out to a competent offering by then, I'm not sure how much I'd be willing to wait when Intel already has a good offering out.

As we presented at Ryzen Tech Day, we are supporting 300+ developer kits with game development studios to optimize current and future game releases for the all-new Ryzen CPU. We are on track for 1000+ developer systems in 2017. For example, Bethesda at GDC yesterday announced its strategic relationship with AMD to optimize for Ryzen CPUs, primarily through Vulkan low-level API optimizations, for a new generation of games, DLC and VR experiences.

Oxide Games also provided a public statement today on the significant performance uplift observed when optimizing for the 8-core, 16-thread Ryzen 7 CPU design – optimizations not yet reflected in Ashes of the Singularity benchmarking. Creative Assembly, developers of the Total War series, made a similar statement today related to upcoming Ryzen optimizations.

CPU benchmarking deficits to the competition in certain games at 1080p resolution can be attributed to the development and optimization of the game uniquely to Intel platforms – until now. Even without optimizations in place, Ryzen delivers high, smooth frame rates on all “CPU-bound” games, as well as overall smooth frame rates and great experiences in GPU-bound gaming and VR. With developers taking advantage of Ryzen architecture and the extra cores and threads, we expect benchmarks to only get better, and enable Ryzen excel at next generation gaming experiences as well.

Game performance will be optimized for Ryzen and continue to improve from at-launch frame rate scores.” John Taylor, AMD

quote:

“Oxide games is incredibly excited with what we are seeing from the Ryzen CPU. Using our Nitrous game engine, we are working to scale our existing and future game title performance to take full advantage of Ryzen and its 8-core, 16-thread architecture, and the results thus far are impressive. These optimizations are not yet available for Ryzen benchmarking. However, expect updates soon to enhance the performance of games like Ashes of the Singularity on Ryzen CPUs, as well as our future game releases.” - Brad Wardell, CEO Stardock and Oxide

quote:

"Creative Assembly is committed to reviewing and optimizing its games on the all-new Ryzen CPU. While current third-party testing doesn’t reflect this yet, our joint optimization program with AMD means that we are looking at options to deliver performance optimization updates in the future to provide better performance on Ryzen CPUs moving forward. " – Creative Assembly, Developers of the Multi-award Winning Total War Series

I agree with this.

But if someone didn't game and wanted to have hobby time editing/exporting dozens of photos in Lightroom and edit/exporting videos in Premier, then would I be correct in thinking that 1700x or 1800x are pretty good options?
