AMD Ryzen 7 5800X3D CPU Pictured, Leaker States ‘No Overclocking Support’ on Upcoming 3D V-Cache Chip
AMD's Ryzen 7 5800X3D CPU samples are out in the wild and it looks like an owner of such a sample has leaked out the first pictures.
AMD Ryzen 7 5800X3D CPU Leaks Out But Reportedly Doesn't Feature Overclocking Support
Most of the picture and the OPN code are blurred out but it looks like the first AMD Ryzen 7 5800X3D chips are out in wild. What's interesting here is that the leaker who posted the picture also states it won't be featuring any overclocking support.
There are several reasons & one we already know is that AMD had to make some tradeoffs for supporting the extra 64 MB of the cache within its first 3D V-Cache chip. The tradeoff made was the lower clock on the X3D chip but it looks like the heat output from the CCD below the cache die can negatively affect it and even break the chip if it's overclocked. Now, this is all speculation from my end at the moment but it's most likely the explanation for the exclusion of overclocking on Ryzen 7 5800X3D CPUs. The other likely case is that this could be an engineering sample that this particular leaker had acquired and doesn't have overclocking enabled.
Frequency is important, frequency is important but every processor, every game is always a series of tradeoffs, bottleneck mitigations and in our architecture, when you are in the range of four and a half to five GIgahertz, four or five is enough when you put a ton of memory on top you know you are not limited by frequency anymore, you are not giving anything up to target that frequency, its the performance limiters or the performance accelerators move up, move elsewhere in the architecture so we can dial back on the frequency a bit ease up on the thermals, make it easier to cool and drop in a big extra blob of cache on top which is more transistor density, more thermal density so that's a trade-off that was very easy.
Update: TechpowerUp is now citing its own sources who have stated that AMD is requesting board makers to remove overclocking options for Ryzen 7 5800X3D. The specific statement reads:
'"5800X3D 8C16T 100-xxxxxxxxx 105 W AGESA: PI 1206b 1/28 Please hide Vermeer-X CPU OC BIOS SETUP options".
AMD Ryzen 7 5800X3D CPU - The World's First 3D V-Cache Chip
The AMD Ryzen 7 5800X3D is going to be the first and only chip with 3D V-Cache based on the 7nm Zen 3 core architecture. The CPU is going to offer 8 cores, 16 threads, and 100 MB of combined cache thanks to its additional 64 MB 3D Stacked SRAM design. Clock speeds will be maintained at 3.4 GHz base and 4.5 GHz boost with a TDP of 105W.
As for the pricing, the CPU is going to feature the same MSRP as the 5800X at $449 US which means that the non-3D chip is going to get a price cut down to either $399 or even lower. The pricing makes the 5800X3D more expensive than the Intel Core i7-12700K which does offer more cores/threads but lower cache. It will be interesting to see performance benchmarks between the two chips.
