Review: Intel Core i3-8100 «Coffee Lake» Tray Sockel 1151-v2 [CM8068403377308]

Core i3-8100 – Intel’s budget quad-core processor from the Coffee Lake family. In contrast to the “stones” of the previous generation Kaby Lake, it operates at lower base frequencies, but it has a larger number of cores. By performance, the processor is practically not inferior to its Core i5 counterparts from the previous Kaby Lake generation, but it is sold for a lower price.

There is no Turbo Boost technology in the Core i3-8100, which means that the chip operates at a constant frequency regardless of how many cores are active at current moment. The processor is worse than the Core i3-7100 when lightly loaded, however, thanks to the four physical cores, there is a noticeable performance increase in heavy distributed loads, where the advantage will be on the side of Core i3-8100.

A larger number of cores use more electricity, so the TDP of i3-8100 is 65 W, as opposed to the 51 W consumption of Core i3-7100.

The processor Core i3-8100 demonstrates surprisingly balanced performance characteristics, especially given its retail price. But due to its mass character and popularity, after two years of selling it did not become cheaper.

Review of Intel Core i3-8100 «Coffee Lake» Tray Sockel 1151-v2 [CM8068403377308]

The Intel Coffee Lake microarchitecture represents the largest generation-level upgrade for more than a ten years.

In the past, Core i3 chips were equipped with two cores that support Hyper-Threading. In Core i3, codenamed Coffee Lake, there are already four physical cores, which makes them analogous to the Core i5 of the previous Kaby Lake generation, but for a lower price.

If you compare Intel Core i3-8100  with other processors, such as the Ryzen 1200, AMD Ryzen 3 1300X and the “stones” of the old generation i5 6400, then the Intel Core i3-8100 “Coffee Lake” shows approximately the same result in work tasks, and in games even on 15-30% exceeds them.

Processor users have noted a lot of positive moments – high clock frequency without overclocking; easy overclocking to 4.9 GHz; its not even heated with an inexpensive tower cooler; works steadily with the latest generation 1080ti video cards; performs well when working with new applications; has a good price for Intel processors.

Testing and comparison with other processors

Comparison of Intel Core i3-8100 with AMD Ryzen 3 1200, AMD Ryzen 3 1300X and AMD FX-8350 processors.

Intel Core i3-8100 cost on computeruniverse.net: € 116.90

AMD Ryzen 3 1300X price on computeruniverse (box version): € 111,90

AMD FX-8350 BOX 8 core (Octa Core) CPU with 4.00 GHz cost on computeruniverse (boxed version) is € 57,90

Tests were conducted using the maximum guaranteed performance of each processor: AMD Ryzen 3 at 2667 MHz, Intel Core i3-8100 – 2400, for AMD FX-8350 – 1866 MHz.

Test: Read, write, copy speed

In terms of speed of reading, copying, writing, the AMD Ryzen 3 1300X processor outpaced all other “stones”. If we evaluate the delay in data access (latency), then Intel Core i3 has the best results, and AMD Ryzen 3 1200 was in last place.

Test: Archiving

AMD FX is the leader in the 7-Zip and WinRar archiving test, and the “Coffee Lake” Intel Core i3-8100 processor worse for 30-40% than the leader.

Rendering tests

The best processor in rendering Corona test is AMD FX . But in the programs V-Ray and x265 leadership holds the processor Intel Core i3-8100.

Cross-platform tests for evaluating processor hardware capabilities

Following the benchmark CineBench R15 results Intel Core i3-8100 gets a silver medal. It is only a few percent behind the leader FX-8350. And in the RealBench program, the processor is again taking the lead.

Game Tests

The game options in Assassin’s Creed Origins were set to the maximum settings for providing high CPU usage and also HD-resolution, so test passes with minimal using of video card resourses. As a result, all 4-core processors were loaded to the maximum. The leaders is Core i3.

Similar results in Far Cry Primal game. But if we to be honest that in the case of the Core i3-8100, the video card was loaded 10-15% higher, that brings the Core i3-8100 to deserved first place.

Core i3-8100 wins the tests in other games: Rainbow Six Siege, WATCH DOGS 2, Rise of the Tomb Raider, Battlefield 1, The Witcher III, GTA V and so on.

More detailed results of game tests can be found in the table below. As you can see, the Core i3-8100 processor in games is ahead of its AMD competitors by 15-30%.

Customer Reviews Intel Core i3-8100 «Coffee Lake» Tray Sockel 1151-v2 [CM8068403377308]

Buyers were satisfied primarily with the performance, price and overclocking potential of the processor.

For a price of i3 6100 processor the buyer gets 4 full cores on a stable 3.6 GHz, which is an excellent option for budget game systems with mid-level video cards (such as GeForce 1060). In fact, the performance of Intel Core i3-8100 “Coffee Lake” reaches the level of i5 7400 – 7500 processors, but for less money. Well, a very nice bonus for overlockers is the ability to pick up the frequency right up to 5000 Mhz, and some buyers even achieve 4.6 GHz at 1.225v, avh 0.

According to the user reviews, the temperature of the processor with a not very expensive Pure Rock Slim cooler is at a mere 30-31 degrees, in stress tests it has only 51-54 degrees.

Disadvantahes is lack of hyper-trading and boost. Buyers also noticed that during overclocking it starts to overheat and the thermal paste quickly dries out.

 

Great performance, low power

April 19, 2018, Size: ProcessorStyle Name: Core i3-8100, Verified Purchase

I set out to make a “nearly” silent PC, in that I didn’t want to go fanless, but I wanted it to have the fans running so slowly (or off) during normal operation that it was silent, and it was only during intensive activities that the fans would ramp up. And I wanted a fair amount of horse-power too so that I could effortlessly do my engineering work (mechanical part creation and PCB layout work mostly). The key to doing that is getting both a CPU and GPU that while high horsepower are also very efficient and then cooling them with well designed heatsinks that don’t take a large amount of airflow and fans that run quietly and allow for very granular control at low RPMs.

For the CPU I’m glad I chose the Intel Core i3-8100. 14 nm technology allows them to have a 4-core processor running at 3.6 GHz but still only generates 65 watts. I don’t think there’s a better combination of horsepower and efficiency on the market right now. It’s a real winner and when paired with the GTX 1050 Ti GPU, this computer rocks while not generating a lot of heat. Measured from the wall outlet, it’s usually below 100 watts total.

But it is also quiet. Pairing this CPU with a good CPU cooler (Cooler Master Hyper T2), a good fan (Noctua NF-B9) and powering it with an EVGA 650 GQ PSU in “eco mode” I have built a truly silent PC in all but the most intensive work situations. Using my pretty sensitive dB meter, I can not detect it being on. I have to do the test in the middle of the night, because even cars going by outside are detectable. But at 3 AM, it reads 21.1 dB with the PC off and 21.1 dB with it on. My stomach gurgles and the stupid thing goes up to 24 dB or I click the mouse and it goes up to over 30 dB so trust me when I say the dB meter is sensitive enough to detect pretty small readings.

To be fair and give a caveat, to keep it silent, the fans are running at 13% on the rear of the case, 10% on the CPU and 5% on the GPU. But that’s just enough air flow with the good heatsinks that in normal operation the system temp stays around 40 and both the CPU temp and GPU temps stay in the mid 50’s.

Build details:
Intel Core i3-8100 CPU
MSI Z370M Mortar motherboard
Gigabyte GTX 1050 Ti “Windforce OC” GPU (Note: Gigabyte is the only vendor with a good fan controller on their 1050 GPU. The other companies have junk 2-pin fans, see my review on that product for more details on how I modded it to be more quiet.)
2 of 4 GB DDR4 2400 Kingston Fury DIMMs
Samsung 960 EVO M.2 SSD
EVGA 650 GQ PSU in eco mode

Customer review from Amazon online shop
Corvette type performance for “Cruze” price.
January 17, 2019. Size: ProcessorStyle Name: Core i3-8100 (Verified Purchase)
Desktop build for CAD/Cam / Internet use client. I combined the i3 8100 with a Gigabyte B360M DS3H motherboard and 16 GB Corsair Vengeance Ram (LPX – 3000 MHz). I like the Rosewill Micro-ATX Mini Tower with its 4 USB ports in the front case cover (2 USB 3.1 and 2 USB 2.0). Also: Samsung 970 EVO 250GB – NVMe PCIe M.2 2280 SSD, EVGA 500-Watt (80+ White) power supply. This PC is the fastest Intel i3 I’ve ever built. My client previously was running an i7 with 16 GB ram. He could not believe how fast this rig was! He compared it to his old split window Corvette he had growing up. The overall combination of the Samsung 970 EVO SSD, 16 GB DDR4, Intel i3 8100 and the B360 system board is CRUSHING performance for just about any challenge.

Conclusion, Advantages and disadvantages

Pros
– high clock without overclocking
– easily accelerates to 4900 Mhz
– not even heated with a tower cooler for 40 euro
– works well with top graphics cards (1080ti)
– works quickly with most applications
– inexpensive, comparing to other Intel “stones”

Cons
due popularity of the processor, the cost after two years of selling did not become cheaper. For example, one of the participants in the first May joint purchase 2018 bought Intel Core i3-8100 box version for € 92.35!

4 streams will quickly become our of date, but for the next few years it will be relevant. Many buyers use it as a temporary option until the release of 8700k.

Conclusion
The processor is very good as a budget or temporary option. According to buyers, even now (the beginning of 2019), it will feel great in the gaming system with a 1060-1070ti video card.
