Intels, i7 10710U, apart from having a lovely name, is a 14nm 10th generation CPU. Just to keep things confusing Intel has both 14nm and 10nm CPUs in their 10th gen lineup.. The 14nm chips are branded as Comet Lake, while the 10nm are Ice. Lake.. The Ice Lake CPUs only currently go up to 4 cores, while the 10710U is the first. U series chip that goes up to 6 cores.! U series CPUs are typically lower power parts for thinner and lighter notebooks, so it will be interesting to see how this new 6 core compares with the popular 9750H. Lets. Look at the differences in specs between these two CPUs., Both have 6 cores and 12 threads 12mb of cache and are based on Intels 14nm architecture.. The main difference is in the TDP. The 9750H has a much higher 45 watt TDP, while the 10710U has a 15 watt. Tdp, though this can be configured up to 25 watts by the laptop vendor, if theres enough thermal and power headroom., This difference in power is why the 10th gen CPU has a much lower base clock speed. The single core turbo speed of the 10th gen chip is 200Mhz faster than the 9750H, however, its all core turbo speed when all 6 cores are utilized is 100MHz behind.. Now heres. The thing the performance of either of these CPUs will, in the end, depend on the power limits that are defined by the laptop theyre installed in.

. For the i7 10710U Im testing the MSI Prestige 15 and when, under a CPU, only workload, its capable of running up to 45 watts so the same TDP as the 9750H.. Technically it can go to 50 and beyond, but PL1 is 45 watts, and this is where it settles.. This will not always be the case. I havent tested any other laptops with this 10th gen CPU yet, but I suspect this could be a best case. Ive tested. The i7 9750H, both at its stock 45 watt limit, which some laptops do actually adhere to, but Ill also include results with the 9750H when the power limit has been raised to 60 watts, as some other laptops also do this and thats the case with the Clevo Nh58Rdq, Im testing with., Basically its not as simple as comparing two CPUs against each other as power limits can play a big role. In this testing. I have tested both the 10th gen 10710U and 9th gen 9750H with the same 45 watt TDP. So the results are about as comparable as we can get.. With that in mind, lets get into those results, starting with Cinebench R20. Ive got the 10th gen 10710U CPU in the middle and 9750H at the same 45 watts down the bottom.. The top result is the 9750H, once its been boosted up to 60 watts, which is more representative of what its typically capable of but as mentioned, it will vary by laptop.

In this test. The 10th gen CPU was 16 ahead of the 9750H in multicore and considering that both have the same 45 watt power limit. This result surprised me., When the 9750H is boosted to 60 watts, though its 8 faster than the 10th gen chip., The 10th gen CPU was 11 faster when it came to single core. This makes a bit more sense when we remember that it does have a higher single core turbo boost. Speed. Ive also tested Cinebench R15, as many people still use it, so these numbers can be used for comparison.. Anyway, the results are similar. The 10th gen chip was ahead by 9 in single core performance, but a much lower 4.6 increase in multi core. Again. The 60 watt 9750H takes the lead by 7.7 in multicore, but was still behind in single core due to the higher single core turbo of the 10710U. Ive run the BMW and Classroom benchmarks with blender and, despite being a heavy multicore test, the 10th gen CPU was Again, ahead of the 9750H, when both had the same 45 watt TDP., The 10710U completed the Classroom test 10 faster and 12 faster for the BMW test., With the 9750H set to a higher 60 watt power limit. Its only just able to take the lead in this test. Ive used Adobe Premiere to export the same 4K laptop review and the 10710U was completing the task 5 minutes faster than the 9750H.. Interestingly, there was no change to the 9750H, even with the higher power limit.

. I was only testing the CPU here. Gpu acceleration was disabled.. Ive also used the warp stabilizer effect in Adobe Premiere, which basically uses a single core to smooth out a clip.. Interestingly, the 10th gen CPU was behind here, which I didnt expect considering. It should have a higher single core turbo boost speed. However, the results were consistent.. Handbrake was used to convert a 4K video file to 1080p and then a separate 1080p file to 720p., With both chips at 45 watts. The 10710U was 10 faster at processing. The 4K file, however, when it came to the 1080p to 720p conversion, the 9750H was slightly ahead.. The V Ray benchmark uses the CPU to render out a scene, and the 10710U was 6.6 faster than the 9750H, when at the same 45 watt power limit. With a higher power limited 9750H, though its able to come out 8 faster than the 10th gen CPU., The Corona benchmark also uses the CPU to render out a scene, and there was a similar result here with the 10710U completing the task 6.4 faster than the 9750H.. With the power limit on the 9750H boosted, its just able to claim the victory. Ive used, 7 Zip to test compression and decompression speeds, and the 10th gen CPU was winning in both cases when it came to compression speed, but was slightly behind in terms of decompression. Veracrypt was used to test AES encryption and decryption speeds, and this time the 10th gen CPU was behind.

In all instances, though, it was only by about 2 or so. GeekBench produced results a bit different to the other real applications. The multicore score was lower compared to the 9750H and the single core was a bit higher, so these results do make sense in the context of the clock speeds of each chip. Heres, a summary of all of the applications just tested. On average over these 18 tests. The 10th gen i7 10710U was 5.2 faster than the 9th gen i7 9750H in both single and multicore workloads, at least when both had the same 45 watt TDP.. Some of the results dont match what I was expecting., For instance, the Warp Stabilizer result at the bottom. I expected the 10710U to win that as its a single core test.. Likewise, I assumed the Cinebench R20 multicore result would have done better on the 9750H, given it has a higher all core turbo boost. Speed. Lets investigate why the 10710U was ahead of the 9750H. In most of these cases., These are the average clock speeds of both CPUs during one of the blender benchmarks., We can see that the 9750H was around 400MHz lower over all 6 cores on average, when compared to the 10710U., The 9750H was only able to match the Clock speed with its higher power limit.: These are the values for CPU package power, as reported by hardware info, while the same blender test was running., The 9750H is basically dead on its 45 watt limit, as per the bottom bar, then, at the 60 watt limit, once Its raised without issue.

, The 10710U, on the other hand, was actually averaging a little below its 45 watt limit, at least in this specific test.. This is because of thermals. The 10710U was thermal throttling in the blender test.. As I mentioned earlier. U, series chips are generally used in thinner and lighter machines, and those typically have less cooling capacity.. This will, of course, vary between each laptop, but in general, youll find the 9750H in thicker machines, with bigger, heatsinks and heatpipes to keep it running cooler., Despite thermal throttling. In blender, the 10710U was still completing the task faster and performing better.. If we look at the total system power draw from the wall for the whole machine, when, under these same tests, the results are even more interesting., The 10710U is using 20 more power than the 9750H in this exact same test, however, as we saw just before, according To Hardware Info both were around their 45 watt TDP. Im, not exactly sure what the deal is here. The difference could simply be down to the changes in Comet Lake.. My 10th gen laptop was clearly using more power to achieve its higher performance as measured from the wall.. The only change I noted in Hardware Info was that the 10710U was reporting as using 4, more watts under IA cores. Anyway. The 9750H machine needed far more power to maintain its 60 watt TDP in this same test, and if you remember it was only just able to beat the 10710U like this.

, Even if the software is reporting incorrectly or there is some architecture difference causing this. The 9750H needed more power from the wall to perform. Similarly in the blender test and achieve similar clock speeds., The fact that the 10710U is competing at all with the 9750H honestly took me by surprise. When I saw its Cinebench performance while reviewing the MSI Prestige 15. I just knew I had to compare the two. Now. Most laptops with the 9750H will run the CPU higher than 45 watts when under CPU only workloads like these but thats, not always the case. It will vary. When both have the same power limit, though the 10th gen chip appears to be in the lead.. The 10710U is also more likely to be lower in other laptops, while the 9750H will pretty much always at least be capable of running at 45 watts.. I should also note that no undervolting was done here. These are all stock results and memory for both machines was 16GB in dual channel at DDR4 2666.. Unfortunately, Im not able to test gaming at this point as I had both laptops with completely different graphics.. The MSI Prestige 15 had the Nvidia GTX 1650 Max Q and Ive never had that in another machine, so cant fairly compare. Pretty much. All gaming laptops are based on the 9750H at the moment. It will be interesting if the 10710U starts popping up in these., Otherwise for thinner and lighter machines with adequate cooling.

The new 6 core 10th gen Comet Lake CPU can perform quite well.. Let me know which of these two CPUs youd pick and why? Down in the comments and if youre new to the channel consider getting subscribed for future CPU comparisons and tech.
