Welcome to the Official AMD Ryzen Threadripper & X399 MegaThread!
This thread will serve as the primary discussion thread for all things regarding Ryzen Threadripper and the X399 platform.
Ryzen Threadripper:
For the first time in history AMD is launching it’s own HEDT platform based on their all new X399 platform. Powering this new platform will be AMD’s Ryzen Threadripper CPUs. AMD promises to bring more connectivity and CPU cores to HEDT than ever before. Threadripper’s flagship, the 1950X sports an astounding 16 cores, 32 threads and 60 PCIE lanes (technically 64 but 4 of those lanes are dedicated to the X399 chipset).
So far, AMD has announced three models of Ryzen Threadripper:
Threadripper 1950X:
16 Cores/32 Threads
3.4GHz (4GHz Turbo w/ 4.2GHz XFR)
32MB L3 Cache
Quad Channel Memory Support up to 2667MHz
Max Temp 68C
Price Tag: $999
Threadripper 1920X:
12 Cores/24 Threads
3.5GHz (4GHz Turbo w/ 4.2GHz XFR)
32MB L3 Cache
Quad Channel Memory Support up to 2667MHz
Max Temp 68C
Price Tag: $799
Threadripper 1900X:
8 Cores/16 Threads
3.8GHz (4.0GHz Turbo w/ 4.2GHz XFR)
20MB L3 Cache
Quad Channel Memory Support up to DDR4-2667
Price Tag: $549
Architecture:
Threadripper is still based off of the Ryzen architecture and still uses the same CCX's as all Ryzen 3, 5, and 7 CPUs. However, what's (significantly) different about Threadripper is it's multi die design (no pun intended), it's been nearly a decade since we last saw mutli die CPUs on the market and those being the Core 2 Quad CPUs from Intel).. In basic terms, Threadripper uses two Ryzen 7 CPU dies to make up it's total of 16 cores and 32 threads, clearly showing the full power and potential of AMD's infinity fabric technology.
However, it's not without it's flaws. Because of AMD's dual dies and massive core count on the 1950X and 1920X, certain games will actually crash due to too many cores being active. Also, because Threadripper is a multi-die architecture, when one or more cores have to communicate with a core or L3 cache on another die (NOT CCX), the latency penalty is very high compared to the likes of Ryzen 7 which only has to deal with core latency between CCX's.
To combat this, AMD has created hardware level CPU modes for Threadripper, something we've never seen before. AMD calls these two modes Creators Mode and Gaming Mode. Creator's mode is the default mode that Threadripper runs as this enables all CPU cores on the chip, meanwhile Gaming Mode completely disables one of the two dies on the CPU, effectively turning the 1950X into a higher clocked R7 1800X. This does improve gaming performance immensely, however because only half of the resources are enabled, it kills any type of content creation performance (like video rendering). You have to restart each time you change modes aswell.
Threadripper Performance:
In Gaming applications, Threadripper does indeed stink at FPS when in it's default mode. However when you switch to Gaming Mode, the performance is quite massive, yielding anywhere from 5 to almost 50% improvements in FPS.
Content creation as of right now is more hit and miss. In programs exclusively designed for rendering like Blender, the 1950X beats the whole competition, however in other applications like Adobe CC which are still single core heavy, the 7700K still beats out the 1950X.
The good news is that Threadripper is VERY new, so optimizations are always needed for a new architecture. I'd expect the 1950X to beat intel's current offerings in almost everything (except gaming) by the end of next year (optimizations will come before that but I mean optimizing as a whole).
Memory Support:
All Threadripper CPUs will run a quad channel memory configuration with a max of 1TB of supported RAM (you can thank EPYC for that). Official memory frequency maxes out at 2667Mhz, though this is just offical, if Ryzen 7 is any indicator Threadripper should be able to hit 3200MHz and above quite easily.
X399 Chipset:
Threadripper will be seating itself into the all new TR4 socket and connected via the X399 chipset. According to AMD specs, X399 is an absolute behemoth of a chipset with a monstrous amount of connectivity that doesn’t even come close to what Intel has done for us since the good ole days of Intel licensing Nvidia to make chipsets for their high end platforms.
X399 Specs:
Quad Channel DDR4 Memory
66 PCI Express Gen 3.0 Lanes (Including the 64 on Threadripper)
8 PCI Express Gen 2.0 Lanes
Nvidia SLI and AMD CrossFire Support
2 Native USB 3.1 Gen 2 Ports
14 Native USB 3.1 Gen 1 Ports
6 Native USB 2.0 Ports
12 SATA 3.0 Ports (With RAID 0, 1 and 10 support)
TR4 Socket:
You thought LGA 2011 was big, think again, the TR4 socket will put all CPU sockets to shame, easily being the largest socket to ever be produced for the consumer market. The TR4 socket by itself is about the size of two LGA 2011 sockets side by side and has over 4000 pins -- almost 2x the amount LGA 2011 has -- for threadripper to seat into.
While this might be cool as a wow factor, it’s most certainly not for CPU cooler manufacturers, the TR4 socket is very challenging to cool with conventional CPU coolers as it is physically impossible to cool the entire IHS with the coolers that we have today. Fortunately companies like Noctua and Fractile Define are already on this and have made new coolers specifically for threadripper.
