AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?

Is it worth paying more money to get the Ryzen 7 3800XT? Or can you spend less and get by with the cheaper 3700X instead? I’ve tested games, applications, power draw, thermals and more to show you the differences and help you decide if the 3800XT is worth the extra.

The specs of these two processors are basically the same, the main difference is when it comes to the base and maximum boost clock speeds.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?The 3800XT is basically just a 3800X with higher clocks, and this is made possible due to improvements AMD have been able to introduce over the last year which result in reduced voltage and improved operating frequencies. AMD noted that with XT processors, bigger gains are expected to single core performance compared to multicore workloads, as the max clock speed will only be reached in lightly threaded workloads.

The main reason I’m comparing the 3800XT against the 3700x, is that the 3700x is AMD’s cheapest 8 core processor in the Zen2 lineup, while the 3800xt is the most expensive. The 3800XT is launching at $400 USD, while the 3700X can currently be picked up on sale for $290, though the standard price is meant to be $330.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU? Both processors were tested in the same system, so same motherboard, 16GB of DDR4-3200 CL14 memory in dual channel, Nvidia RTX 2080 Ti graphics, and Fractal S36 AIO with the same thermal paste.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU? Although the 3700X and 3800X for that matter do come with stock coolers, the new 3800XT does not. All testing was done with the same Windows updates and Nvidia drivers installed. With that in mind we’ll start out with the application tests, followed by overclocked results, power draw, thermals, then gaming tests at 1080p and 1440p afterwards.

Starting with Cinebench R20, I’ve got the newer but more expensive 3800XT up top, and the older but cheaper 3700X below. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?In this test the 3800XT was 4% faster when it came to multicore performance, however the single core score had a higher 6.5% boost.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU? I’ve also tested the older Cinebench R15 as a lot of people still use it, and the margins were quite similar, with again a larger improvement noted in single core performance, which makes sense and is expected as the max boost clock improvements are utilized here.

I’ve tested the Blender BMW and Classroom benchmarks. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?This is another threaded test, so the 3800XT was only around three to four percent faster than the 3700X in these tasks.

AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Handbrake was used to convert 4K  video to 1080p, and the 3800XT was only completing the task around 3% faster than the 3700X. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Adobe Premiere was used to export video at 4K, and the 3800XT was only 1.7% faster here, or about 40 seconds faster in a task that takes over 40 minutes to complete.

Premiere was also tested using the Puget systems benchmark tool. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?This tests more than just exporting such as live playback, and this test saw the smallest improvement on the 3800XT out of all applications I’ve looked at. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?I’ve also tested the warp stabilizer effect in Adobe Premiere which is a less threaded workload and is used to smooth out a video clip, and the 3800XT was just 3.5% ahead, I thought it would see a bigger gain due to the higher max boost clock but it wasn’t too different. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Adobe Photoshop was another that was tested with the Puget Systems benchmark tool, and the 3800XT was only scoring a percent higher in this one.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU? 7-Zip was used to test compression and decompression speeds, and the 3800XT was only around 2% faster when compared to the 3700X. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?VeraCrypt was used to test AES encryption and decryption speeds, interestingly the 3700X was a little ahead in both cases, the 3800XT was actually scoring a little lower here, and it was consistent as I’m using the average of 10 runs. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?The V-Ray benchmark uses the processor to render out a scene, and like most other core heavy workloads the difference was minimal, with the 3800XT scoring less than 3% higher. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?The Corona benchmark also uses the processor to render out a scene, and the result was very close, with the 3800XT again about 3% faster than the 3700X. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?In the Hardware Unboxed Microsoft Excel test the 3800XT was actually slightly slower, but it was extremely close, about a one percent difference, and given there is a little variance in this test between runs I’d say it’s margin of error. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Like other single core tests, the Geekbench single core score had one of the highest improvements out of all applications tested, with a 5% higher score on the 3800XT, while the multicore score saw a 2.5% improvement.

Here’s how the newer Ryzen 7 3800XT compares against the older Ryzen 7 3700X from one year ago. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?In most cases the 3800XT was ahead, and we can see that the single core tests are mostly towards the top of the graph, indicating that single core performance seems to have larger gains when compared to multicore performance with these new XT processors.

I’ve also done some tests with both processors overclocked. I was able to get my 3700X stable at 4.3GHz over all 8 cores at 1.375v, and using the same voltage on the 3800XT I was able to run it at 4.5GHz, the highest I’ve ever been able to get a Zen2 processor with minimal effort, so it would appear that the improvements they’ve incorporated over the last 12 months are helping there, but these were by no means finely tuned overclocks.

These are the results in Blender with the stock results at the bottom and overclocked results above.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU? The 3800XT overclock was allowing it to complete the task around 5% faster, while the 3700X’s overclock sped it up about 4%. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Cinebench illustrates some interesting behaviour, by manually overclocking in this manner and statically setting all cores to a speed, the all core boost speed becomes lower than the maximum single core speed at stock, so although multicore workloads see gains, single core performance is actually slower here, you’d probably be better just enabling PBO. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?When we look at the total system power draw from the wall with the blender test running, the 3800XT was using more power to achieve this higher performance, and both needed about 6 watts more for the overclocks, despite the 3800XT being pushed further. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Higher power draw typically results in more heat, and for the 3800XT it was running a couple degrees warmer with the overclock in place, though interestingly my 3700X was actually a bit cooler while being overclocked and performing better, and this was because my manual voltage setting was better than what the motherboard was applying by default, but this will vary based on how you tune it. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?These are the clock speeds that were being reached during these tests, so at stock the 3800XT was around 120MHz faster than the 3700X in a solid multicore workload, though the gap widened with the 3800XT’s superior overclock.

Let’s get into the gaming results next, I’ve tested 13 games at both 1080p and 1440p resolutions. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Shadow of the Tomb Raider was tested using the games benchmark tool. I’ve got the 1440p results above the 1080p results, and the 3800XT was just a couple of FPS ahead at either resolution, putting it around 2% faster.

Now that I’ve set your expectations appropriately, let’s look at Battlefield 5, the game that saw the biggest improvement from the 3800XT out of all 13 titles tested. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?The average FPS was similar at 1440p, however at 1080p the 3800XT was consistently 9% faster, then when we look at 1% lows the 3800XT was well over 30% faster there. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Assassin’s Creed Odyssey was tested with the games built in benchmark, and the 3800XT was around 3% faster in terms of average frame rate when compared to the 3700X at either resolution. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Call of Duty modern warfare was tested in campaign mode, and I’ve done the same test pass through the game with each processor. The results were very close, however the 3700X was slightly ahead in all cases, an interesting result but yeah just a few frames. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?The Division 2 was tested using the games benchmark tool, and the gap was even smaller here, so not really much we can draw any meaningful conclusions from. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?CS:GO was tested with the Ulletical FPS benchmark, and despite being a game that typically thrives with higher CPU clock speed, the 3800XT was only delivering frame rates around 1% faster than the 3700X. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?The difference in Dota 2 looks similar, but at 1080p the 3800XT is now 2.5% higher in average FPS, lowering to a 1.5% higher frame rate at 1440p, again not really something you’re likely to notice in practice. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Control is typically more GPU heavy, so it wasn’t much surprise that at high settings the two processors were offering essentially identical performance.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Red Dead Redemption 2 was tested using the games benchmark tool, and once more there was no real noteworthy difference between the two chips.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU? The Witcher 3 actually saw slightly lower performance with the 3800XT, similar to Call of Duty, not really sure why that was the case given the 3800XT should be pretty similar just with higher clock speeds. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Overwatch was tested in the practice range, while performing better than actual gameplay it allows me to perform the exact same test run. Anyway the results were similar to the last game, where the 3800XT was a little behind the 3700X. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Ghost Recon Breakpoint was tested with the games benchmark, there was a little edge to the 3800XT in average FPS, though it’s still small, just 1.6% ahead of the 3700X at 1080p and 2.7% ahead at 1440p.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU? Far Cry New Dawn was also tested with the games built in benchmark, and there was an above average difference here, even if it doesn’t look like it - the 3800XT was 3% faster at 1080p and 2% at 1440p.

AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?On average over these 13 games tested, the Ryzen 7 3800XT was just 1.4% faster when it came to average frame rate at the 1080p resolution.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU? Interestingly when we step up to 1440p the difference is actually less on average, as a few games seemed to do a little better on the 3700X here, either way though only small changes one way or the other. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?If we instead look at the differences to 1% low performance, as this is typically where the processor is more sensitive, the 3800XT now had a 4% lead over the 3700X, though a lot of that would be down to the huge Battlefield 5 win. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?Similar deal at 1440p, the 3800XT was still 3% ahead on average in 1% lows. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?When we look at the results in terms of dollar per frame values, the 3700X is offering far better value. This makes perfect sense, it’s over $100 cheaper but as we saw, in most of the games tested the frame rates were very similar. AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU?If we instead look at the cost per frame values for the 1% low results, the margins don’t really change, the 3700X is still far better value owing to its price point.

Outside of gaming, as we saw, the 3800XT does perform better, but for 37% higher cost these results seem pretty difficult to justify to me.AMD Ryzen 7 3800XT vs 3700X - Which 8 Core CPU? You could of course make the argument of time is money, and you’re happy to pay more for more performance, but even that doesn’t hold up here as you can get the 12 core 3900X for just $30 more than the 3800XT, and if you’re doing multicore workloads like rendering then I’d expect that to offer better value.

So the 3800XT is a welcome addition given it comes in at the price point of the 3800X last year, but the improvements in that time aren’t really enough to make it worthwhile when the existing Ryzen processors that have already been out for a year now can be picked up for such great prices.

Personally at this point I’d probably just wait for Zen3, which is apparently on track for release this year in 2020, but otherwise if you are after an 8 core processor, the Ryzen 7 3700X looks like a better pick for most people when compared to the more expensive 3800XT. Let me know which CPU you’d pick and why down in the comments.
