Time has subsequently come. Today we're bringing you our complete evaluation of the Threadripper 2990WX and Threadripper 2950X. Although these two CPUs proportion the same basic DNA, you ought to know they are very one-of-a-kind processors, focused on completely one-of-a-kind marketplace segments.
Since they have been introduced in advance this yr, everyone's attention has been fixed firmly on the 32-core/64-thread 2d Gen Threadripper component, now referred to as the 2990WX, coming a Boxt $1800. There may be two fashions in the WX collection and for the ones thinking the 'W' signifies that this is a workstation series and the 'X' the standard xtreme nonsense we suppose. Along with the 2990WX there can also be a 24-core/forty eight-thread model called the 2970WX, though that model gained’t be available until October.

Although the TR 2990WX has been receiving all the attention, we assume the 2950X to be the actual hero of this new lineup in what basically is a elegant 1950X at a $100 lower release rate.
As was the case with the 2nd Gen 5 2600X and Ryzen 7 models, those new Threadripper components characteristic decreased cache and DRAM latency with aid for slightly faster memory. So they may be based totally on the Zen+ architecture which uses the 12PL technique from GlobalFoundries.
The TR 2950X features the identical format as the 1950X and which means it incorporates two lively Zeppelin dies, every packing eight cores, memory channels and 32 PCIe gen three lanes. When the usage of DDR4-3200 reminiscence the Infinity Fabric throughput among those dies is kind of 50 GBps.
As was the case with the 1950X, the 2950X can be configured in one among two ways. Using UMA (Uniform Memory Access), which AMD refers to as ‘disbursed’ mode of their Ryzen Master software, the processor acts as a unmarried unit and this means threads and DRAM transactions are disbursed evenly across the complete chip to maximise bandwidth, but in turn will increase latency which isn’t best for obligations together with gaming.
Therefore it's miles possible to allow NUMA (Non-Uniform Memory Access) which AMD refers to as 'local mode' within the Ryzen Master software program. They name this a nearby working mode as the processor is separated into domains and attempts to pair active cores with nearby DRAM, in preference to accessing memory via a controller Box + separate die which comes with a as a substitute hefty latency penalty.
The 2990WX then again is a completely specific beast. It includes no longer Zeppelin dies but alternatively 4, enabling as much as 32 cores. However at the X399 platform AMD has imposed some barriers to keep away from cannibalizing their single socket EPYC server CPUs.
The largest of these obstacles being that there are nonetheless just four reminiscence controllers. Although there are greater Zeppelin dies, the additional two dies are compute dies, in AMD’s phrases. This means they don't have any nearby PCIe or DRAM get entry to, for that they should tour via the Infinity Fabric to the IO dies. As there are twice as many dies, the Infinity Fabric bandwidth is likewise halved, so now the throughput among dies is simply 25GBps, assuming you’re the usage of DDR4-3200 memory.
Because of this layout that sees of the dies without direct get right of entry to to the DRAM, it manner that unlike the 2950X, the 2990WX makes use of NUMA solely. AMD says that this quad-NUMA configuration has allowed them to create the world’s first 32-center patron processor, and just as essential, it has allowed them to do it even as retaining backwards compatibility with existing TR4 merchandise.
There is an apparent drawback that’s had me a chunk concerned because we first heard approximately this 32 center version. We always knew that 1st Gen Threadripper CPUs had the capability to offer as much as 32 cores, so this isn’t a few kind of radical step forward for AMD with the second Gen series. The authentic Threadripper chips didn’t have 'dummy' dies as claimed with the aid of AMD. We continually knew they had been faulty or disabled Zeppelin dies, those are in any case simply EPYC CPUs for the laptop. Though we don’t mean to sound like we're downplaying whatever here, EPYC CPUs at the laptop could be very a great deal epic.
Anyway, for this second Gen Threadripper collection AMD has enabled those extra dies to create the 24 core and 32 middle fashions. The hassle is reminiscence bandwidth, as there certainly isn’t going to be sufficient of it. We still only have quad-channel memory access, so memory bandwidth stays the same, however now we have two times as many cores to feed.
Likely this is going to make an already niche product, even greater targeted, so hold that during thoughts. For checking out we’ve got a truckload of facts and while we tried to encompass as many CPUs as feasible we did run out of time to replace the results with the i7 -8700K.
The accurate news is we have consequences for some of Intel’s excessive-end laptop processors inclusive of the Core i9-7980XE and 7960X, for example. Basically all structures had been configured with 32GB of DDR4-3200 memory using XMP timings. So permit’s get into the consequences.

Benchmarks
Okay nicely we might as nicely get this one out of the manner first, Cinebench R15. As a lot of you are in all likelihood aware of through now given AMD leaked the results, the 2990WX achieves a score of simply over 5000 pts in it’s stock out of the field configuration. That makes it a whopping 52% faster than the Core i9-7980XE and at this factor you are likely thinking what the hell I changed into a Chip:bout once I stated there were a few disadvantage to the layout, however keep that notion for now.
Anyway in this particular synthetic rendering benchmark the 2990WX has no problem blowing socks off. The 2950X is no slouch either although it does most effective improve upon the 1950X by way of an insignificant 5% margin.
Next up we've got every other rendering benchmark although this one is primarily based on actual-global software program. The Corona Renderer has been used to test workstations with over 64 cores, so it scales thoroughly. Here we once more see breathtaking rendering performance from the 2990WX as it took simply forty one seconds, permitting it to complete the take a look at 40% quicker than the 2950X, no longer best core scaling but still an outstanding result. This additionally meant it became 28% faster than Intel cutting-edge flagship Core i9 component. Also this time the 2950X turned into simply 4% faster than the 1950X, so every other small gain, but a ga+ Corell the same.
Moving on I fired up the Ryzen Graphic workload in Blender, that is a noticeably brief check for excessive-give up CPUs and we see that with the 2990WX which took simply 8.3 seconds. This meant it finished the workload 36% faster than the 2950X and 31% quicker than the Core i9-7980XE.
Aga Core-8550Un extraordinary final touch time for the 2990WX however it needs to be said for a doubling of cores we're most effective seeing a fifty five% increase in overall performance while in comparison to the 2950X and there's simplest a totally minor clock pace distinction among the two. So what about a workload that takes considerably longer than a few seconds for the 2990WX to finish.
Disappointingly the a whole lot extra complicated and therefore longer to finish Gooseberry workload become less favorable to the 2990X. Okay so it nonetheless uprooted the 7980XE and kicked in it’s pins, however it become also only able to lessen the of entirety time by way of a 28% margin while as compared to the 2950X. It turned into also capable of reduce the render time by using 20% when compared to the extra costly 7980XE, in order that’s apparent a extraordinary end result for AMD.
Still it’s a troubling signal that during what should be an superior workload for the 2990WX, we’re simplest seeing a 38% boom in performance, for a a hundred% boom in cores.
Okay so POVray is the ultimate rendering benchmark we’re going to look at and this one bodes properly for the 2990WX. Here it become capable of reduce the rendering time by way of 40% while in comparison to the 2950X and this supposed it become sixty five% faster, so once more now not exquisite scaling but 65% is lots better than what we noticed in Corona and Blender. It changed into also fifty seven% faster than the Core i9-7980XE, so a huge win there.
I’ve covered the heavy multitasking outcomes from RealBench which runs image enhancing, video compressiChip: AMDnd rendering duties simultaneously. The 2990WX saw a top load of 70% however for at the least half of of the check load became down round 20%, in order that’s really worth noting. Here we see the 2990WX imparting a quite negative end result taking forty three seconds to finish the workload.
This made the 32-core processor slower than even the 1950X. Here it became the 2950X that impressed, matching the Core i9-7960X and 7980XE. This meant the 2950X changed into in a position to finish the heavy multitasking test 6% faster than the 1950X, so agai7-8550U Ultraportable exceptional result.
