Intel Core i7 vs i9: Differences & Performance

You might agree with me that the latest laptops in the market are mainly ones with Intel processors. Currently, the recent processor upgrade has ushered in the Intel Core i9 processor.

The Intel Core i9 is a higher variant of the previous Core i7 processor, but how will you identify them?  Also, how does the performance boost influence the price?

Now, in this article, we reviewed two identical MSI GT75 Titan 8RG laptops with similar specs but with a difference in their core processors to help know their differences. If you want to know more about the modern core i7, check out another tech-focused resource.

The embedded Core i7 and i9 processors in GT75 are 8th generation CPUs from the Coffee lake series.

The Differences between Intel Core i7 and i9 Processors


The Intel Core i7-8850H and Core i9-8950HK are the names of processors embedded in MSI GT75 Titan 8RG laptops.

These processors are both Hexa-core capable of processing 12 threads at a time. The Core-i9’s has a clock able speed at 2.9GHz or 4.8GHz (at max-turbo) while Core-i7 comes at a speed rate of 2.6 GHz’s or 4.3 GHz (at max-turbo.

Also, when it comes to cache Core i7 can store only 9MB of cache while Core i9 can hold 12MB. The greater smart cache enables the processor to remember common functions and execute them at faster speeds.


Although there are no considerable changes in the build and surface of the laptops, the price difference is considerable. The two laptop model comes at a price tag of $2,800 (Core i7) and $3,300 (Core i9). This makes a considerable price difference between the MSI GT75 Titan 8RG laptops.

Overall performance

In measuring the average performance of the processor models, several tests were carried out. One of them is the Geekbench 4 test, which measures the overall performance of core speed and memory.

In this test, GT75 Titan 8RG’s Core i7 scored a 17,639, while Cores i9 scored 19,514, making it 9.4% faster. On overclocking core i9, an output of 21,204 was generated, which is a 16.8% increase over Core i7.

The performance of the Cores was measured relative to 18,709 premium gaming laptop average.

Video Transcoding

Here the Handbrake benchmark was used stating how long it takes to transcode a 6.27GB, 12 minute, 30-second 4K video to 1080p.

Core i7 version took 9: 06 minutes (beating average time of 9:58) while Core i9 completed the task in 8:31 minutes, giving a 35-second gap. On overclocking the Core i9, the task was completed in 8:23 timeframe, giving a 9.2% gap from Core i7.

Excel Test

An Excel Test which requires striking 65,000 names against corresponding addresses was carried out. In which MSI laptop (Core i7) averaged more than 0:43 category at 36 secs and Core i9 at 33 seconds. The overclocked Core i9 performs the task one second faster.


These laptops were placed on gaming benchmarks to test the performance by a few popular magazines.

Impressively the MSI laptops are top gaming models packaged with Nvidia GeForce GTX 1080 GPUs along with 8GB VRAM.

The Core i7 averaged 71 fps (frames per second), which is above the 60fps gaming average. The Core i9 gives an 80 fps average result making it 10.1% better than Core i7. However, overclocked Core i9 gave similar rates to Core i7 at 71 fps.

A Hitman gaming benchmark was tested on 1080p settings with DirectX 12 enabled (showcasing top-notch visual effects) for the two processor models.

The Core i7 gave a 95 fps above the 89-fps average. While, the Cores i9’s performed better at 107 fps, and the overclocked Core i9 gave the same result.

The Grand Theft Auto V benchmark showed both the Core i7 and Core i9 to be quite similar. The Core i9 gave an 84 fps average while Core i7 showed 83.6 fps, with a mere 0.5% difference.

The overclocked Core i9 also showed an 84 fps performance. However, the results were impressive relative to the 74-fps category average.


The best processor to get depends on what you need it for.

However, you should consider getting the Core i9 for a graphics-intensive task, 3D modeling, video editing, or other high-tasking programs like music production.

This is because the laptop with Intel Core i9 surpasses the Core i7 in its raw performance.

Any casual user who needs to play games and occasionally uses high-tasking programs can always opt for a Core i7 laptop.
