Differences in 3 Types of Intel Core i7 Processors

Intel Core i7 9750H, Intel Core i7 10510U, and Intel Core i7 1065G7 are the Intel Core i7 processor lineup that are most often found on the market today, of course, these three processors also have their own focus and target users. For an example of performance in this content, we use the example on the HP brand. Before going any further, let’s start with the specifications first



These three processors have different names. Intel Core i7 9750H is called Coffee-lake, Intel Core i7 10510U is called Comet-lake, while the last one, Intel Core i7-1065G7 is called Ice-lake. Coffee-lake is the name for the 9th generation of Intel processors, while Comet-lake and Ice-lake are the names given to the 10th generation. Although both are the 10th generation, Comet-lake and Ice-lake have differences in IGP, base clockspeed , turbo boost speed, and its fabrication technology.

Power Consumption

Although both are Core i7, these three processors have different power consumption. On the i7 9750H, the TDP is 45W. Whereas on both 10th generation Intel processors, the TDP is 15W. To test how long these three processors can operate a laptop without a charger, we simulated it using PCMark 8 Home Conventional with Power Saving mode on, WiFi and backlit keyboard turned off and brightness set to the lowest.

The result is in accordance with the resulting TDP. The i7 9750H with a TDP of 45W can run the laptop in less time than the i7 10510U and 1065G7. Both 10th gen processors have longer runtimes, which is normal. Besides the battery capacity, the TDP of both processors is 30 watts smaller.

With these test results, the use of the i7 9750H processor in a full load scenario makes users unable to stay away from electricity, in contrast to the i7 10510U and 1065G7 which have better results. However, the i7 9750H on this HP laptop is classified as having a good battery consumption for a processor size of 6 cores 12 threads.


For your information, Intel has several lineup of laptop processors, including the HK series which indicates that the processor is a high-performance and overclockable processor, then there is the Y series which indicates that the processor is a processor that is really power efficient, exceeding the U series, which usually found on laptops with small and thin screen sizes.

The H series or the 7th gen and below is called the HQ series, placed as a series with high performance without overclocking capabilities, while the U series is a series of processors with low power consumption, in contrast to the G series which is devoted to processors with fast IGP, usually the IGP used is Intel Iris Plus Graphics but there are also those using IGP Radeon Vega. For performance testing, we used GeekBench 3 Pro, Cinebench R15 and 3D Mark Firestrike.

In the GeekBench test, if sorted, the i7 9750H has the highest score, followed by the i7 1065G7 and 10510U.

Based on the test results, the i7 9750H achieved the highest score. This can be seen from the multicore score for the i7 9750H which reached 22670, with such a high score, the processor is very suitable for heavy usage scenarios such as gaming and content creation. As for the other two processors, the score is quite high for the size of a laptop with a small weight but in terms of singlecore the U and G are higher than the H series. This is because the turbo boost on Comet-lake and Ice-lake is very high. With its high turbo boost, it will be very helpful in office and browsing scenarios. Because the scenario is quite light, it doesn’t require a lot of cores but a high clockspeed.

As for the memory score, the i7 1065G7 has the highest score among other processors, this is because this processor already uses 3733Mhz memory speed.

In testing Cinebench R15, it is clear that the i7 9750H has a far superior advantage over the i7 10510U and 1065G7 with 1235cb. Even though it has a turbo boost speed that is smaller than the i7 10510U, the higher number of cores and threads can provide higher performance than the other two processors. This will be better suited for jobs that require a higher number of cores and threads, such as heavyweight video rendering.

The same goes for his single core score. Although the i7 9750H has a lower turbo boost speed than the i7 10510U, thanks to its high TDP and more cores, its performance is above the U or G series.

Besides that, even though the scores produced by the i7 10510U and 1065G7 are smaller than the i7 9750H, the score is still relatively high for a processor with a small TDP. But still we don’t recommend the U and G Series for heavyweight video rendering use. Maybe if you are still learning or still light, for example video editing under 1 minute, this processor is still capable of that.

Switching to 3D Mark Firestrike, the i7 9750H is still superior in this test. With a fairly large score difference, this processor is much better at handling gaming scenarios than the other two processors. We also had time to test the i7 10510U processor with single-channel RAM, the results obtained were much lower than the results with a dual-channel RAM setup. The test results can be seen in the following image.

Target User

Each Intel processor has a different target user. For those of you who have high mobility, a laptop with an Intel Core i7 1065G7 processor is the right choice. This is due to its efficient power consumption but has a fairly fast performance with a fairly thin body. In addition, a high memory clock will add to the experience in terms of CPU performance and the IGP, because the memory in the IGP uses memory on the CPU.

Meanwhile, if you also have high mobility but still often play games, or content creation, a laptop with an Intel Core i7 10510U is the answer. Because this CPU class is usually paired with NVIDIA series GPUs, so in some scenarios that require graphics speed, the MX series GPU on this laptop can help a little.

Lastly, if you are the typical user who spends most of the time sitting around playing games or editing videos, a laptop with an Intel Core i7 9750H processor is a good choice for you. Because in general, H series processors are always paired with a GTX or RTX GPU. with component configurations like this, usually what is sacrificed is in terms of weight, battery life, and dimensions. Although it can still be carried anywhere using a large bag, the portability of a laptop with hardware like this cannot be compared to a laptop with a low TDP processor.


With each of its advantages, these three i7 processors have different designations and target users. There are those that have high performance with rather wasteful power consumption but are very suitable for heavy usage scenarios, there are also those that have economical power consumption but so-so performance so that they are only suitable for light-light usage scenarios such as office / browsing / presentations in front client. Of course, every person’s choice and every product made by a brand, there must be a target user.
