I have been offered a used system including an intel 7700K processor. Right now I have a 3570K. I know the 7700K is faster, but is it going to be a noticeable improvement for gaming and 3D work? I'd use my current GPU (GTX 1070) so basically it'd boil down to: 3570K 16GB DDR3 vs 7700K 16GB DDR4 3000mhz
I guess the question would be, is your current CPU hamstringing your GPU? If so, the 7700K would be an improvement - PassMark has it at about a 25 percent boost single-thread, near-double overall. If not, then it ain't going to make much of a difference at all - but will improve non-GPU stuff a fair chunk.
Thanks Gareth. I know, it's a weird, question, I am trying to gauge real life performance. I have seen the benchmarks, but is Autocad going to run noticably better due to 25% faster single core performance? To put things in perspective: In the past I have upgraded from a 3Ghz Pentium 4 to a Q6600 quad core, which obviously made everything feel much faster. Then I had the 3570K system which included an SSD - again, huge noticable improvement in every regard. I don't want to spend 500 quid to have a system that feels the same as the old one if you know what I mean.
If it's going to cost you £500, then no. £500 will get you a Ryzen 3600+decent AM4 board and 16GB 3000Mhz DDR4!
I don't use AutoCAD myself, but these guys seem to say it's a GPU-heavy workload benefiting from a good GPU, scads of RAM, and a good CPU in that order. These guys, though, say that having a high single-core speed is more important than having lots of cores when it comes to the CPU. So: upgrading the CPU should improve AutoCAD's performance - but you may get more of a boost by throwing that £500 at a new GPU and another 16GB of RAM instead.
Thanks guys. Sorry, I should have made myself clearer. 500 quid is for a whole system: Decent PSU, case mainboard, etc. RX 580 256GB SSD 2TB HDD I thought I would gut the newer and my old system, swap my better GPU and SSDs with the one in the above rig and still be left with a perfectly fine second rig for gaming when my brother is around.
500quid would get you into one of the latest boards,cpu, ram and ssd that would be superior to 7700k but I guess it depends on what you will get back for the left over parts from two systems as to whether the 7700k is a good value upgrade.
I went from a 3570 to a 7700 and there was a big difference, made even bigger when you factor in faster boot times from an m.2 drive. I'll have some benchmark scores at home so can give you definitative score based improvements later.
A stock 3570k will bottleneck a 580 GPU. Obvs a touch of overclocking will help that, but faster GPU could be hamstrung.
Thanks again guys. I'd have two full systems (but I'll not list case, mainboard, psu etc, they are medium range but fine): 7700K 16GB DDR4 1,5TB SSDs 1070 GTX 3570K 16GB DDR3 256GB SSD 2TB HDD RX580 But I think I am not going to buy that system. I'd be second guessing my decision too much.
I moved from a heavily overclocked 3570k to a mildly overclocked 6800k and the only real difference is the ability to run NVMe SSD's I'd say. Games run faster, but they ran fairly fast anyway. I can now game and watch stuff at once a bit better, but truth be told, there's not a massive improvement to be had. A 9900k would probably feel better because of lots of cores at super speeds, but then thats crazy expensive. The CPU experience itself probably won't feel any different.
In terms of Autocad specifically, using the 4690k as a proxy for the 3570k (because I couldn't find anything that still included old Ivy Bridge CPUs directly against Kaby Lake) it should be a minimum 40% performance uplift with GPU performance kept constant (the Quadro P6000 is like a suoped-up Titan Xp). Performance will actually be higher as the 4690k is a decent amount faster than the 3570k on its own. In terms of gaming, again using the 4690k as a proxy, changes could be anywhere form naf-all to a decent bump depending on the game. Techreport have a more direct comparison with a smaller selection of tests.
Heck, for £500 you can get a 3700X and with a B450 board and 16GB! Proof - https://uk.pcpartpicker.com/list/XbwKHB Personally I'd rather put these parts in my existing PC than buy the 7700K, if I had the money and was ready for an upgrade in general.
Will it not allow you to use an M.2 drive? I noticed a significant difference using Word with referencing software Mendeley. The other thing is how long is your 3570K platform going to last? I upgraded from a 2500k because of stability issues.
