The AMD Zen and Ryzen 7 Review: A Deep Dive on 1800X, 1700X and 1700

When AMD launched the Wraith cooler last year, bundled with the premium FX CPUs and highest performing APUs, it was a refreshing take on the eternal concept that the stock cooler isn’t worth the effort of using if you want any sustained performance. The Wraith, and the 125W/95W silent versions of the Wraith, were built like third party coolers, with a copper base/core, heatpipes, and a good fan. In our roundup of stock coolers, it was clear the Wraith held the top spot, easily matching $30 coolers in the market, except now it was being given away with the CPUs/APUs that needed that amount of cooling.
That was essentially a trial run for the Ryzen set of Wraith coolers. For the Ryzen 7 launch, AMD will have three models in play.
These are iterative designs on the original, with minor tweaks and aesthetic changes, but the concept is still the same – a 65W near silent design (Stealth), a 95W near silent design (Spire), and a 95W/125W premium model (Max). The 125W models come with an RGB light (which can be disabled), however AMD has stated that the premium model is currently destined for OEM and SI designs only. The other two will be bundled with the CPUs or potentially be available at retail. We have asked that we get the set in for review, to add to our Wraith numbers.
Memory Support
With every generation of CPUs, each one comes with a ‘maximum supported memory frequency’. This is typically given as a number, with the number aligning with the industry standard JEDEC sub-timings. Technically most processors will go above and beyond the memory frequency as the integrated memory controller supports a lot more; but the manufacturer only officially guarantees up to the maximum supported frequency on qualified memory kits.
The frequency, for consumer chips, is usually given as a single number no matter how many memory slots are populated. In reality when more memory modules are in play, it puts more strain on the memory controller so there is a higher potential for errors. This is why qualification is important – if the vendor has a guaranteed speed, any configuration for a qualified kit should work at that speed.
In the server market, a CPU manufacturer might list support a little differently – a supported frequency depending on how many memory modules are in play, and what type of modules. This arguably makes it very confusing when applied at a consumer level, but on a server level it is expected that OEMs can handle the varying degree of support.
For Ryzen, AMD is taking the latter approach. What we have is DDR4-2666 for the simplest configuration – one module per channel of single rank UDIMMs. This moves through to DDR4-1866 for the most strenuous configuration at two modules per channel with dual-rank UDIMMs. For our testing, we were running the memory at DDR4-2400, for lack of a fixed option, however we will have memory scaling numbers in due course. At present, ECC is not supported ECC is supported.

If you have a Q6600, I can understand that, but the QX9650 ain't too bad. ;)Marburg U - Monday, March 6, 2017 - link
I'm on a Q9550 running at 3.8 for the past 6 years. I could still run modern games at 1050p, with a r9 270x, but that's the best i can squeeze out of it. Mind that i'm still on DDR2 (my motherboard turns 10 in a few months). I really want to embrace a ultra wide monitor.mapesdhs - Monday, March 6, 2017 - link
Moving up to 2560x1440 may indeed benefit from faster RAM, but it probably depends on the game. Likewise, CPU dependencies vary, and they can lessen at higher resolutions, though this isn't always the case. Still, good point about DDR2 there. To what kind of GPU were you thinking of upgrading? Highend like 1080 Ti? Mid-range? Used GTX 980s are a good deal these days, and a bunch of used 980 Tis will likely hit the market shortly. I've tested 980 SLI with older platforms, actually not too bad, though I've not done tests with my QX9650 yet, started off at the low end to get through the pain. :D (P4/3.4 on an ASUS Striker II Extreme, it's almost embarassing)Ian.

I'm actually using a Q9550 that's running at 3.8 as well. I have a 980ti and it can do 4k, albeit at 25-30fps in newer games like Witcher 3. Fairly certain a 1080ti would work great with a Q9550, but I feel like the time for these chips is coming to an end. Still incredible that a 8 year old chip can still hold it's own by just upgrading the GPUmapesdhs - Tuesday, March 7, 2017 - link
Intriguing! Many people don't even try to use such a card on an older mbd, they just assume from sites reviews that it's not worth doing. Can you run 3DMark11/13? What results do you get? You won't be able to cite the URLs here directly, but you can mention the submission numbers and I can compare them to my 980 Ti running on newer CPUs (the first tests I do with every GPU I obtain are with a 5GHz 2700K, at which speed it has the same multithreaded performance as a stock 6700K).What do you get for CB 11.5 and CB R15 single/multi?
What mbd are you using? I ask because some later S775 mbds did use DDR3, albeit not at quite the speeds possible with Z68, etc. In other words, you could move the parts on a better mbd as an intermediate step, though finding such a board could be difficult. Hmm, given the value often placed on such boards, it'd probably be easier to pick up a used 3930K and a board to go with it, that would be fairly low cost.
Or of course just splash for a 1700X. 8)

Welcome to the 21:9 fan club brother.But be careful of the 1920x1080 screens, my brother's 21:9 doesn't look half as good as my 3440x1440 screen.. It just needs that little bit more verticle resoultion.
My pals 4k screen is lovely, and brings his 4GB 980 GTX to its knees. Worse aspect ratio (in my opinion), and too many pixels (for now) to draw.
Careful of second-hand purchases too, many panels with backlight-bleed issues out there, and they are returns for that reason, again, in my opinion.

Long story short:20% lower single-thread than Intel
70% higher multi-thread due to 8 cores
$330-$500

Actually, on average -6.8% IPC versus Kaby Lake (at the same frequency) - I believe this came directly from AMD. Add to this a lower grade 14nm process (GF again) that is biting AMD again and again (see last year RX480). Motherboard issues (memory, HPET), OS/application issues (SMT, lack of optimizations).All in all, I'm really impressed of what they achieved with such obstacles.

Just looking at CineBench at a given TDP and price, AMD is 20% lower. That's the high level answer, regardless of IPC * clock frequency. I agree it's a huge win for AMD, and for users who need multicore performance.Cooe - Monday, March 1, 2021 - link
Maybe compare to Intel's Broadwell-E chips with actually similar core counts.... -_-
