Is a $600 CPU 10x MORE POWERFUL than a $60 one?

2017-09-12
when I first saw the pentium g 4560 at $64 earlier this year i thought gee the core i7 6850 is almost exactly 10 times the price we should see if it's at all worth it but we kind of missed the boat on that one because the core i9 is here now so I mean who we even care about this comparison anymore anyway wait we'll just use its replacement the core I 978 20x and we'll just agree to disagree about how many times 64 goes into 600 synergy allows you to share your mouse and keyboard between multiple computers at once check it out now at the link in the video description let's get this out of the way right now we are not expecting the pen TMG 4560 to go toe-to-toe with the kora 978 20x that's stupid I mean for one the core I 9 has turbo boost to say nothing of the six extra course that it's packing under the hood well ok Linus then what is the point of this video I'm glad you asked first since one is roughly 10 times the cost of the other we thought this would give us a good feel for how pricing scales with performance within intel's product stack because i think obviously we're not gonna be getting ten times the performance with the car I know hey will be no we've been through that that's stupid reason number two is that this will give us some interesting insight into bottlenecks and where they show up within the system for example will the rebalanced cash and avx-512 support of the core i9 help it will it hinder it will it depend on the workload how much will the extra cores help with real-world tasks does it even really matter now I know I know raw performance isn't the whole story the core I 9 has more than double the PCI Express Lanes quad-channel memory support blob and those features don't come cheap so it makes sense that you'd be paying a premium for both the CPU and the accompanying motherboard and because the core i 9 demands a better cooling solution surprise you get to buy one of those two they even require more thermal compound thanks to their larger physical size I mean the Pentium comes with a cooler and compound that's more than adequate for it right out of the box so then with all these differences how can we possibly compare the two easy we'll just dump a bunch of benchmarks into Excel like we always do and wait really it's not all I'm paying these guys for oh no there's more here actually oh cool okay so while we'll be running the two chips on otherwise identical hardware we are also going to run a second set of tests on the 7820 x with it configured with only two cores enabled and clocked like a G 4560 so in the past this method of cutting down higher-end chips has generated pretty accurate simulations of lower end ones but today the new cache setup in support for avx-512 might make things a little more interesting our gaming results well okay these ones aren't gonna shock anybody our simulated 4560 does slightly better than the real thing and the stock 78 20x blows the doors off of both in every test but while that difference is measurable our arch nemesis dr. point of diminishing returns makes a bold appearance here interestingly our simulated chip actually fell slightly but measurably short of the real one at 4k and csgo and in 3d mark which makes us wonder where else we might see Intel's new caching mechanism perform worse bottom line here if you thought that spending 10 times was gonna net you 10 times the performance in gaming ah I believe as the gamers say get rekt productivity though was really interesting in applications like why cruncher that support avx-512 we saw a massive difference with the simulated g40 560 while in more traditional tasks like Cinebench cpu mark and real bench the cache related performance boost is less exciting with real benches and coding tests revealing another situation where it may actually cause a slight performance regression it's not over for the simulated chip though because our real-world blender test also sees a huge performance boost over the real 4560 in productivity applications the lack of a DX and course hurts our value chip big-time the 7820 ax still doesn't give you ten times the performance for its price but given that many of these workloads are business oriented ones time is money and even a 2x performance improvement or a more modest one could allow it to pay for itself over time so your mileage may vary power consumption is probably not gonna surprise anybody some will skim through that but what might is the performance scaling using some simple math helpfully provided by Alex we crunched the numbers and calculated a very theoretical ballpark for how pricing would look if it's scaled linearly with performance so in that world from the perspective of bokura 978 20x the performance averaged price of the Pentium would actually be roughly five times as expensive as it is today then looking at it the other way around the price of the core I 978 20x would work out to about a quarter of its current MSRP of $600 so what did we learn today well first and foremost that CPU pricing at least for Team Blue is more complicated than just how does it benchmark on a test bench and then you know what price tag should we slap on it and more importantly perhaps we've also confirmed that skylake X's new cache generally helps more than it hinders though it can hinder situationally there are a hundred reasons for wanting multiple computers at your desk maybe you're a Mac person primarily but you need a non virtualized Windows environment for some reason synergy solves the problem of having to have two keyboards and two mice for two or more separate computers you can share one set of peripheral so you'll no longer get confused and the whole thing is seamless you just drag the mouse from one screen to another we're talking peace Mack and even Linux support they offer a basic and pro option for synergy with a one-time payment and features include advanced stuff like clipboard sharing between computers dragging and dropping files between computers the ability to set up hotkeys and more so use our link in the video description to get 50% off synergy today so thanks for watching guys that this video sucked you know what to do but if it's awesome get subscribed hit that like button or check out the link to where the buy the stuff we featured in the video description also down there is our merch store with cool shirts like this one and our community forum which you should totally join so you can talk shop with other tech enthusiasts from around the world
