AMD THREADRIPPER VS INTEL SKYLAKE X

If these chips are representative they are going to offer some seriously impressive performance, albeit at a price.

that's what it's always been about though isn't it (relatively speaking)

intel/nvidia = best performance
amd= price/performance

if you're someone like me, thats happy to spend whatever they deem necessary to get the best performing pc, then you're more than likely (since the last 10 years or so) going to have an Intel/amd build.

if you want decent performance for less money, you're going to have an amd/amd build.

for example I was happy to spend the extra money on a titan Xp + evga hybrid setup to get that extra 7% performance from my you, most people will never do this as it is, in all honesty terrible price/performance.

Skylake-X 10c/20t @ 4.8 GHz is going to kick some serious ass. Rumoured to be $1000 though, not exactly targetted at home users.

definitely, the ones to watch for are the 6 and 8 core, should hit those clocks a bit easier due to less heat imo. and £600 for the 7820x is actually pretty good for the performance you get.

True enough, certainly can't disagree with that.

Even the i7-7820X (8c/16t) looks like it's going to be around double the price of an R7 1700 though (with a more expensive motherboard to boot), plus it doesn't have many more PCIe lanes either (28 vs 24 I think?).
 
Intel i9-7900X Review

https://www.bit-tech.net/hardware/2017/06/16/intel-core-i9-7900x-and-x299-chipset-revie/1

Regarding heat:

However, temperatures were definitely a concern with Cinebench and Terragen pushing 100°C with our 240mm AIO liquid cooler. As a result, while stable and potentially tameable under custom water-cooling, we decided to go for 4.6GHz for benchmarking, which required a super-low 1.22V. Interestingly our Core i7-6950X ran much cooler despite using a significantly higher voltage, albeit at 4.4GHz. This could well be due to thermal paste having been used between the heatspreader and CPU core with the new Skylake-X CPUs, in which case delidding could potentially yield significant benefits given the high heat density.

depends on your use case I suppose? you do have 24? lanes provided by the chipset on intel, which can be dedicated to nvme, sound cards etc.

I mean sli only needs x8/x8 and crossfire x4/x4 so there's enough for a mgpu setup.

more importantly is out of the bog figures, this is 4.3ghz all core boost standard and the 1700 is 3.2ghz all core, so you're paying for higher ipc+ 1.1ghz higher clockspeeds, which is fairly significant for a workstation that mostly never get overclocked.

Nothing Special, he says, with an external VRM board hooked up to the motherboard, and 1.5v.

I wouldn't trust cpu-z voltage as it's often wrong, well at least I know my 7700k isn't running 1.6v lol.

but, if it is correct that's auto voltage doing it's thing and pushing far more voltage than necessary for the clocks.

Interesting, i haven't looked at it all yet but already on the first page already i'm seeing Skylake-X with 20% more cores only 28% faster than the 8 core 1800X in Handbreak, next one down, photo editing... the 10 core 7900X is 5% faster than the 1800X.

So what happened to Intel's so called 30% IPC lead? it seems to have all but completely evaporated....

Oghhooo reading on it doesn't get much better..... not even in games.

A thousand pound for this?

So basically the heatspreader TIM is trash and will affect overclock potential, as expected.
