Okay, the Comet-Lake-H CPUs are here, or should we say Coffee Lake-HR or Coffee Lake-H? The Comet-Lake-H architecture is Coffee Lake-based so there are a lot of similarities between them. The new architecture is characterized by a 14nm+++ process, all CPUs can boost higher than their predecessors, and the memory controller supports higher memory frequencies – 2933 MHz.
Today we are going to compare the Intel Core i7-10750H and Core i7-9750H. The i7-10750H is the successor of the well-know i7-9750H which is widely used in a lot of gaming machines and it is (or was) the Intel’s sweet spot for powerful mobile devices. The latter is still very powerful and it offers a much better price/performance ratio than its 8-core siblings and at the same time, it’s clearly faster than the 4-core ones (especially when it comes to multitasking).
At least on paper, the Core i7-10750H is a bit disappointing – the base clock is the same, the cache size is the same, and the TDP levels are again – the same. Yes, the Turbo clock is higher thanks to the Thermal Velocity Boost but this kind of clocks are available only below 70°C so it’s up to your machine’s cooling. In short, while you’re gaming or maybe editing videos (or some other CPU-intensive work) the all-core boost will be away from the 5.0 GHz mark and from the Turbo Boost clock too (which is different than the Thermal Velocity Boost) – 4.80 GHz.
A bit above we said “disappointing” because when the i7-9750H was released it has 3MB bigger cache size than its predecessor – the i7-8750H (yes, the evolution is the following – i7-8750H – i7-9750H – i7-10750H) and that leads to some positive advantage in games and in some other specific programs. Unfortunately, in today’s case, we have a modest bump in terms of boost clocks and memory frequency. That’s all but it is what is, let’s see how the new one will perform against the older one and keep in mind that they are very similar.
As always, we are starting with bulk prices – $395.00 for both. It looks easy – probably the faster chip wins the match. The two CPUs have 6 cores and 12 threads, as well as 12MB cache size. In terms of frequencies, the base clock is the same no matter the processor – 2.30 GHz. The boost clock of the Core i7-10750H is a bit higher (4.80 GHz to 4.50 GHz) and thanks to Thermal Velocity Boost it can go up to 5.0 GHz.
When it comes to the max supported memory frequencies, expectedly, the new one has the upper hand – it supports DDR4-2933 RAM. The iGPUs are the same – Intel UHD 630 and even the clocks are equal (350 MHz – 1.15 GHz) so you can expect similar performance here but don’t forget the fact, that most of the Core i7-10750H machines will be equipped with a dedicated graphics, just like the Core i7-9750H ones.
|Intel Core i7-10750H||Intel Core i7-9750H|
|Cores / Threads||6/ 12||6 / 12|
|Base / Max frequency||2.60 – 4.80 (5.00) GHz||2.60 – 4.50 GHz|
|Cache||12 MB L3 Cache||12 MB L3 Cache|
|TDP / up / down||45W / – / 35W||45W / – / 35W|
Nothing unusual, the Core i7-10750H is ahead of the Core i7-9750H by just 6% – nothing to write home about. Keep in mind that these scores can be lower or even a bit higher than the ones in this article because if the CPU cooling solution is weak, the overall performance is taking a deep dive or vice versa.
Results are from the Cinebench 15 CPU test (the higher the score, the better)
Results are from the Fritz chess benchmark (the higher the score, the better)
Expectedly, the performance of the Intel Core i7-10750H is very close to the Core i7-9750H levels. That’s normal, these are almost the same chips, no matter the fact that the newer one is using a bit refined 14nm+++ process and the older chip is a 14nm++ product (yep, a lot of pluses here). Who would buy the Core i7-10750H? Probably a lot of users that prefer Intel over AMD will get a machine with this CPU (if they need something at a reasonable price with more than 4 cores) because sooner or later the Core i7-9750H will be out of stock (ergo, discontinued).
This means that you can wait a bit for a good deal regarding some laptops with the Core i7-9750H – when the market is full of Core i7-10750H-based laptops, the prices of the older chip-based devices will go down. Does the Core i7-10750H make any sense? Well, sorta. Essentially, it’s not a big deal when it’s compared to the Core i7-9750H. If you don’t look at the numbers from OSD software or benchmarks it’s really hard to spot the difference between these two.
If you need a new Intel machine right now and if you found a good deal on a machine that has a Core i7-9750H – it’s not a bad choice. This CPU is still good enough for games, streaming, and maybe something heavier like photo and video editing. If you’re hesitating between two laptops with Core i7-10750H and Core i7-9750H and the prices are close maybe you can get the one with the newer CPU. On the other side, AMD has pretty good deals right now too and it’s worth it to check them because the end prices are lower than the Intel’s (at least in most cases).
