Amd ryzen 7 3700x vs i9

This is a much-needed comparison of two processors with similar characteristics, but with a large price difference. The Ryzen 7 3700X occupies 8 cores and 16 threads just like the i9-9900K. Although this AMD processor was probably not intended to specifically compete against the i9 (If the Ryzen 7 3800X), still, the improvement in the IPC of the Zen 2 architecture is enough to see it battle in front of the team's flagship blue. Let's see who is the winner.

AMD Ryzen 7 3700X

This processor is the intermediate proposal of the new Ryzen 3000 series, above the Ryzen 5 3600 and a few steps below the Ryzen 7 3800X and Ryzen 9 3900X. The interesting thing about this processor is that the TDP is the same as that of the Ryzen 5 3600 (65W) but with two additional cores.

The chip reaches 4.4GHz with its boost clock (fully loaded). Its price, today, is about 360 euros approximately.

Intel Core i9-9900K

The flagship that Intel currently has for the consumer market. The processor, which costs more than 500 euros, has been on the performance podium since it was launched in the last quarter of the year last year. However, AMD with its Ryzen 3000 series is jeopardizing his reign.

The chip has 8 cores and 16 threads and reaches a maximum of 5.0GHz with a single core and 4.7GHz on all cores.

Game performance tests

To perform these tests in games, an AORUS Master X570 board was used as a base to test the Ryzen and an RTX 2060 graphics card. The memory used is the 16GB @ 3600MHz G.Skill Trident Z RGB Royal.

All 6 games were tested in 1080p, 1440p resolution and 4K with the highest quality.

In 1080p resolution

Games (average FPS)	Ryzen 7 3700X	i9-9900K
Shadow of the Tomb Raider	104	98
Far Cry 5	115	113
DOOM	150	130
Final Fantasy XV	103	101
Deus Ex: Mankind Divided	93	100
Metro Exodus (Without RTX)	105	130

In 1440p resolution

Games (average FPS)	Ryzen 7 3700X	i9-9900K
Shadow of the Tomb Raider	71	67
Far Cry 5	82	69
DOOM	119	118
Final Fantasy XV	68	70
Deus Ex: Mankind Divided	63	68
Metro Exodus (Without RTX)	41	58

In 4K resolution

Games (average FPS)	Ryzen 7 3700X	i9-9900K
Shadow of the Tomb Raider	38	38
Far Cry 5	42	42
DOOM	73	60
Final Fantasy XV	36	36
Deus Ex: Mankind Divided	33	40
Metro Exodus (Without RTX)	25	3. 4

We see that the Ryzen 7 3700X outperforms the i9-9900K in 4 of the 6 in-game tests, with a noticeable difference in DOOM. However, the Intel option wins in two games by a not insignificant margin, in Deus Ex and Metro Exodus, especially in the latter. It can be concluded that things are rigged in games and will depend on each title and how it is optimized to see a difference between both processors.

Considering the value of both processors, the balance is tilted to one side quite clearly.

Productivity Performance Testing / Benchmarks

We know that many users use these processors not only for gaming, but also for other, even more demanding, tasks.

	Ryzen 7 3700X	i9-9900K
AIDA 64 - Reading Speed	51, 062 MB / s	50, 822 MB / s
AIDA 64 - Write Speed	28, 734 MB / s (may be a bad read from the software)	51, 751 MB / s
Cinebench R15 (Single-core)	205 cb	214
Cinebench R15 (Multi-core)	2149 cb	2057 cb
3DMark Fire Strike	24, 753	24, 902
Blender (Less is better)	152.52 sec	156.93
Wprime 32M (Multi-core) (Less is better)	2, 731	5, 079
Wprime 32 (Single-core) (Less is better)	24, 881	28, 214
PCMARK 8	4637	4664

In the different synthetic tests, we again see a parity, in Cinebench or 3DMark. On the other hand, we see advantages for the Ryzen 7 3700X in Wprime and Blender very clear. The i9-9900K clearly wins at AIDA 64 and memory write speed.

Consumption and temperatures

	Ryzen 5 3700X	i9-9900K
Consumption (Rest) (W)	70W	49W
Consumption (Load) (W)	295W	261W
Temperature (Stock) (°)	37 °	29 °
Temperature (Load) (°)	45 °	80 °

The temperatures at which the Ryzen 5 3700X works are great, with only about 45 degrees of temperature. Here we note the inclusion of the 7nm node. We hardly need to buy any additional heatsinks. The i9-9900K, meanwhile, works at temperatures of 80 degrees with a Corsair H100i V2 liquid cooling (no heatsink comes in the box). In this case, it is recommended to buy a third-party heatsink to at least make it work. Ains Intel…

As for consumption, both are on par, with 295W and 261W, with an advantage for the AMD option, again.

Final words and conclusion about AMD Ryzen 7 3700X vs Intel Core i9-9900k

With this parity and slight performance advantage, in addition to operating temperatures under 50 degrees with the stock heatsink (Wraith Prism with RGB LED) and a price difference of around 150 euros in favor of the Ryzen 7 3700X, we believe that there is no doubt what is the most recommended option at this time to build an 8-core, 16-wire Gaming PC.

If this processor is combined with an X570 motherboard, we will also get the advantage of PCIe 4.0, which is important for new PCIe SSDs, which benefit from higher read and write speeds.

We will see what will be the next movements of Intel, in terms of price drops and the new processors planned to update its current Coffee Lake refresh proposal.

WE RECOMMEND YOU Nvidia will show a new Tegra chip in August
