Any 5960x users? some questions.

[AlienALX]

1. What exact speed do all 8 cores boost to stock? 3.3ghz?
2. What was your stock Cinebench score? around 1200 points?

Basically I have had this X79 set up for a couple of years, maybe more actually. Ever since I built it I had an Ivy EP chip in there with 8c 16t that boosts to 2ghz on all 8 cores. It's absolutely fine for pretty much everything but then a 2680 v2 came up (not the retail 10 core, the ES 8 core) that on paper at least seems to have very similar speeds and so on as the 5960x. Stock speed is 2.8ghz but the boost speed is 3.6, meaning I should get around the same as the 5960x on full boost.

Also being Ivy EP and having the same sort of cache structure as the 5960x it should be pretty close.

Fannytastic ta.

Just leaving that there.. I have seen it score 1290 or so and as low as 1200 so I guess it depends on how good the board is etc. Will leave that there as a point of reference Still looking now but what is the stock turbo for all 8 cores? I know it says 3.5ghz but that is usually for one/two cores on every other Intel CPU and then it slows down as the core count gets used up.

 

[tinytomlogan]

Turbo is board dependant, some manus will just make all of the cores go to the max, some dont. There is no one answer and it really comes down to how your board does it. The DLX just max turbo'd all cores

Wicked cheers. That probably explains why you scored so well at stock

So if I can get boost to around that speed I am expecting it to be within 10-15% of the X. Might run Cinebench at 2ghz and then do the maths on IPC with the speed % added.

Edit. OK did some calculations. First I ran Cinebench on my 2ghz Ivy. @ 2000mhz I scored 671. However I am using the PC (listening to a DVD of a live band).

So I did some maths. if I score 671 then I should score half of that at 1ghz. If I calculate it down to 1gb it makes it easier to multiply.

So let's say 335.5 points at 1000mhz. 3.5 x 335.5 is 1174cb points.

OK so doing some more maths. If the 5960x scores 1400cb and the 3.5ghz Ivy scores 1174cb at the same clocks that means that the Ivy has 83.86% of the 5960x's stock performance. So 16.14% faster than the Ivy at the same clocks. This could well make sense.

I'm going to reduce the load on the rig, then run CB again. Let's see how accurately I can predict my new CPU's performance

-------------------------------------------------------------------------------------------------------------------------------------

Edit. Round 2 ! This time I opened up task manager and shut as much down as I could so that I got the CPU down to 0-1% of use at idle. Obviously doing this freed up the CPU more, so the score was as follows.

Much better ! so let's do some more maths.

723 @ 2000mhz. Divide by two to get the 1000mhz score = 361.5.

361.5 x 3.5 (for 3500 mhz) = 1265cb score.

1265 is 90.36% of 1400, so the Ivy chip is 9.64% slower than the Haswell one.

So, I am predicting a score of anywhere between 1150 and 1300 when it arrives

It has the same cores, cache etc as the one I have now.

OK so my maths turned out to be pretty darn accurate !

I lucked out, because I thought I had a Rev 1 and checked CPU support and thought it supported the CPU. Then some one pointed out to me the other day that it had a very small N/A next to it to the far right of the chart because it doesn't work.

I checked my board and miraculously it turned out to be a Rev 1.1 which supports everything due to better phases, even the 12 cores (so I have room to upgrade lmao).

The only "not so good" news is that it does not boost to 3.5ghz on all 8 cores. It "only" boosts to 3.1, but that is still an 1100mhz upgrade on all 8 cores for £100.

So clock for clock it's actually faster than what I thought. Clock for clock it's easily within about 8% of the 5960x

So I think this will now definitely be my daily beater. Temps on Prime 95 are in the high 40s on all 8 cores and it's virtually silent. The only way for me to beat it with my 5820k is 4.6ghz (which yields around 1280 points) but it's not fully stable. For that I need to overclock to 4.4ghz which means I drop to around the same score as the new Xeon only I am now overclocked with nearly 1.3v running through the CPU. This would definitely shorten the life of the board. Every time I have ever overclocked a big ass CPU the board has failed.

So yeah, pleased as punch really. Just need some more RAM and a SSD for my games and it'll be sorted

Will try some more benchmarks soon.

CPU is a brute, absolutely thrilled with it
