welcome back to hardware on box today's video is a bit of an informative one if you're deciding what sort of laptop you need we'll be comparing the core i7 8750 h against the core i7 8550 you in a wide range of productivity workloads to see how these to 8th gen parts stack up this should give you an idea of how much faster the au 750 h is and whether you need the power provided by this H series CPU relative to the more power efficient 8550 you before getting into the numbers let's talk specifications the core i7 8750 H is an 8th gen coffee-like CPU for high-performance mobile devices it has a 45 watt TDP and for that you get 6 cores 12 threads and nine megabytes of l3 cache there's a base clock of 2.2 gigahertz but it can boost up to four point one gigahertz on up to 2 cos 4.0 gigahertz on four course and 3.9 gigahertz on six cores the core i7 8550 U is a KB Lake refresh CPU that sits in Intel's 8th gen lineup it's designed for low to medium power ultraportable laptops packing four cores and eight threads into a 15 watt TDP plus eight megabytes of l3 cache the base clock is a rather low 1.8 gigahertz though it boosts up to 4 gigahertz on up to 2 cores and 3.7 gigahertz on for cause obviously the key difference here is the core count with the 8750 H getting 2 extra cores at similar clocks to the 8550 you however the integrated GPU in both chips is very similar the 87 58 uses Intel's UHD 630 while the 8550 you uses the HD 620 the both GPUs have the same 24 execution unit so the only real difference is GPU clock speed in any case as the eye 78758 is often paired with a discrete GPU graphics workloads and gaming isn't really a focus of this comparison our eye 78758 test system is the gigabyte Aero 15 X which we've reviewed previously on the channel if you're interested for these tests we've disabled the discreet nvidia geforce gtx 1070 max q GPU and also upgraded the system to sixteen gig of dual channel ddr3 for our I 78550 you test systems we have two laptops one is the Dell XPS 13 which is configured to use the 85 50 use maximum 25 watt TDP up state the other is the razor blade stealth which uses a standard 15 watt configuration let's get into the benchmarks and we'll start with Cinebench r15 here the 8750 h holds an enormous 83 percent performance lead over the 25 watt 8550 u which is down to having 50% more cores and increased capacity for higher clocks the clock speed discrepancy grows with the 15 watt 8550 you hear the 8750 edge holds at 124 percent advantage so it's more than twice as fast the 8750 h holds a much more modest performance lead in the single threaded test it's nine percent faster than the 15 watt variant and seven percent faster than the 25 watt variant the a 750 H holds a similarly large performance advantage in x264 encoding looking at the more intensive second past the 8750 h is a good 87 percent faster than the 85 50 used 25 watt variant and 116 percent faster than the 15 watt variant roughly speaking the coffee-like processor provides double the performance in rendering tasks which is critical for those that want to edit or render videos on these sorts of laptops the Delta between the two CPUs is slightly small in handbrake while rendering x265 videos but it's still pretty large the 8750 H is a hundred and six percent faster than the 15 watt variant and 77 percent faster than the 25 watt variant of the 85 50 you Excel is a short workload that completes in a few seconds so here the fast boosting 8550 you can narrow the margin to a decent extent that said the a 750 H is still faster than the 25 watt variant to the tune of 56% and as our 15 wash'd test system actually manages higher burst clocks due to different tuning it narrows the margin to an even 50% what about Adobe Premiere well in our 4k video rendering benchmark with some GPU accelerated effects but no luma tree color in this instance the 8750 h holds a significant 61% performance lead on the 15 watt 8550 u and a 57% lead on the 25 watt moral matlab is highly memory bandwidth dependent with modern CPUs in basic processing tasks like FFTs and OD es hence why the difference between the 8750 H and 8558 is so small we're only looking at a five to seven percent performance lead to the 8750 h compared to the 8550 you it's a different story in 7-zip the 8750 h manages to outperform the 15 watt 85 fifty-year by 42% in compression and 66% in decompression in this workload as the Dell XPS test system we have doesn't reach as high both clocks in short workloads again two different tuning as I mentioned earlier the 87 58 holds a huge 82 percent performance leading compression and 105 % it decompression it's important to note the tuning does affect how the 8550 performs in their sort of short workloads so the range of results you can see here is pretty common unfortunately I couldn't get Pacey mark 10 to run on the Dell XPS 13 but we can see how the 8750 h performs relative to the 15 watt 8550 you in this test looking at the overall score the a 750 H is 14% faster though it does manage a 31% performance lead in a Productivity workload performance is near identical in the digital content creation workload and that's likely due to a GPU bottleneck in Adobe Photoshop while applying an iris blur to a large image the 8750 H was 25 percent faster than the 15 185 50 and 19 percent faster than the 25 watt variant this is one of the smaller performance deltas but it does still give the 8750 h a convincing performance advantage if you're interested in IG PU performance I will briefly mention some 3d mark results in the cloud gate test we see the 8750 H take a 5% lead on the 25 watt 8550 U and a 16 percent lead on the 15 watt variant most of this is down to a superior CPU score with an e identical GPU score but in the more GPU limited skydiver tests this lead is eradicated which isn't a surprise the integrated GP of both ships is basically the same so we've now seen how the eye 78758 stacks up against the eye 78552 and the results probably won't come as a massive surprise when you pick a 45 watt CPU with more cause against a 15 watt cpu designed for low-power systems the 45 watt CPU should win in every scenario and by a large margin the biggest performance gains in favour of the 87 50h are seen in a video rendering and other long workloads so if you're thinking of purchasing a laptop for video editing the a 750 H could give you double the performance in some cases it does HD CPUs are designed for these sorts of professional workloads and it shows in shorter multi-core workloads like Excel and archive decompression the performance difference between the two CPUs is closer to the difference in core counters but CPUs manage similar bursts clock speeds still with 50% more cores in the a 750 H that translates to around 50% more performance where you won't see as significant performance gains is in single threaded tests where the 8750 h only has a single-digit performance lead on the 8550 U and in integrated graphics performance where both GPUs are basically identical what CPU is right for you will depend on the sort of things you plan to do professionals that want to render videos work with large images compiled code run simulations and so forth will be much better off with the AI 78758 particularly if these tasks are multi-threaded however if you aren't just planning on browsing the web editing documents or basic spreadsheets and doing some light photo editing the I 78550 is perfectly fine particularly as these less intensive tasks tend to be more single-threaded where the 8550 you compete strongly with the 8750 h that's it for this quick cpu comparison if you like this video don't forget to give it a thumbs up subscribe
