9700X vs 7800X3D- Which Ryzen 7 Is Better for Gaming?
The 9700X vs 7800X3D choice confuses many people. Both chips have 8 cores. Both use the AM5 socket. The 9700X is newer, so it should be faster, right? In games, it is not. The Ryzen 7 7800X3D is the better gaming CPU. In launch tests it led the 9700X by about 8% at 1080p, and by over 20% in some CPU-heavy games. At 1440p and 4K the gap shrinks to a few percent. The 9700X is faster for heavy work.
This guide compares the Ryzen 7 7800X3D vs 9700X using real review data, and answers the questions gamers ask most, one by one.
Table of Contents
| Your situation | Better pick | Why |
|---|---|---|
| Gaming at 1080p or 1440p with a high refresh monitor | 7800X3D | It led by about 8% at 1080p in two separate tests |
| Gaming mostly at 4K | Either one | The lead was only about 2% at 4K in MuyComputer’s test |
| Gaming plus video editing or coding | Depends | The 9700X was 14% to 25% faster in work tests, but Digital Trends still picked the 7800X3D for mixed use |
| Simulation games like Stellaris | Either one | GamersNexus saw the 9700X finish 3.9% faster |
| Heavy rendering most of the day | Neither is ideal | A chip with more cores fits better |
| Already own a 7800X3D | Keep it | GamersNexus saw no reason to upgrade on AM5 |
How we compared: this guide uses published review data. We did not run our own lab tests. Most head-to-head tests below are from August 2024 launch reviews. BIOS and Windows updates since then may help the 9700X a little, so treat the numbers as a guide, not a promise.
What Are the Ryzen 7 9700X and Ryzen 7 7800X3D?
Both chips are made by AMD. Both have 8 cores and 16 threads [threads let each core do two jobs at once]. The big difference is cache.
Cache [very fast memory built into the chip] works like a desk next to a chef. A small desk means the chef keeps walking to the storeroom. A big desk keeps everything in reach. The 7800X3D has a huge desk. The 9700X has a small one.
| Spec | Ryzen 7 9700X | Ryzen 7 7800X3D |
|---|---|---|
| Design | Zen 5 (newer) | Zen 4 (older) |
| Cores / Threads | 8 / 16 | 8 / 16 |
| Base / Boost Clock | 3.8 GHz / up to 5.5 GHz | 4.2 GHz / up to 5.0 GHz |
| L3 Cache | 32 MB | 96 MB (3D V-Cache) |
| Rated power (TDP) | 65W | 120W |
| Overclocking | Yes | No (locked) |
| Socket | AM5 | AM5 |
| Cooler in the box | No | No |
Specs from Notebookcheck’s comparison page and TechSpot’s 9700X listing.
Here is the surprise. The 9700X runs at a higher clock speed, but the 7800X3D has three times the cache. In many games, cache matters more than clock speed.
7800X3D vs 9700X – Which One Is Faster in Games?
The 7800X3D. How much faster depends on the game.
TechPowerUp’s 9700X review found the 7800X3D had an 8% lead at 1080p. MuyComputer’s review found almost the same: 8.07% at 1080p. Two different sites landed on the same number, which is a good sign.
An average hides the real story, though. Here are the per-game results from the GamersNexus launch review of the 9700X, all at 1080p:
| Game (1080p) | Result |
|---|---|
| Baldur’s Gate 3 | 7800X3D led by 23% |
| Dragon’s Dogma 2 | 7800X3D led by 21% (109 FPS vs 90 FPS) |
| F1 24 | 7800X3D led by 20.5% |
| Final Fantasy XIV: Dawntrail | 7800X3D led by 10% |
| Stellaris (simulation time) | 9700X finished 3.9% faster |
The pattern is simple. Games with lots of NPCs, AI and world data love the extra cache. Some simulation games, like Stellaris, care more about core speed, and there the 9700X won.
This is why “the 9700X is basically the same” is true for some games and wrong for others. If you search for ryzen 7 9700X vs ryzen 7 7800X3D, this per-game spread is what most pages skip.
A myth to skip: you may see a claim that the 9700X is 2% faster. That came from an early AMD pre-launch claim reported by Overclock3D. TechPowerUp noted that AMD later said its Zen 5 chips would not beat the 7800X3D in games, and the independent tests above agree.

Does Your Resolution Change the Answer?
Yes. It is the most important question to ask before you buy.
At 1080p, your graphics card finishes frames fast, so the CPU becomes the limit. At 1440p and 4K, the graphics card takes over. MuyComputer measured exactly this:
| Resolution | 7800X3D average lead over the 9700X |
|---|---|
| 1080p | 8.07% |
| 1440p | 3.21% |
| 4K | 2.11% |
Source: MuyComputer, August 2024.
GamersNexus saw the same thing at 1440p. In Final Fantasy XIV the 9700X was about tied with the 7800X3D. In F1 24 both chips were held back by the GPU, so GamersNexus called them the same. TechPowerUp said that at the very GPU-limited 4K setting, even the older 5800X3D matched all the competitors.
One catch: upscaling (DLSS or FSR) makes the game draw at a lower size first. That gives the CPU more work. So a 4K player who uses upscaling may still see a small CPU gap.

What About Smoothness and Stutter?
Average FPS is your normal speed. 1% lows are your slowest moments, and they decide whether a game feels jumpy.
GamersNexus reported that the 9700X’s lows were mostly in line with its averages in the games above. So when the 7800X3D wins by a lot on average, it usually wins on lows too. On the LTT forum, one user said that moving from a 7700X to a 7800X3D gave a nice increase in lows in the MMO games they play. That is one person’s experience, not a benchmark, but it fits the pattern.
9700X vs 7800X3D- Which One Is Better for Work and Editing?
Here the story flips. The 9700X has higher clocks and no cache penalty, so it is better at heavy tasks.
- MuyComputer measured the 9700X about 21% faster in Cinebench R23 single-core and about 25% faster in multi-core.
- Digital Trends found the 9700X finished an x265 video encode 14% faster than the 7800X3D.
But there are two honest warnings. First, Digital Trends still said the AMD Ryzen 7800X3D is the one to buy even for mixed workloads, and only suggested the 9700X for people who do not game at all. Second, MuyComputer said that if heavy apps are your top priority, a chip with more cores, like the Ryzen 9 7900X, may suit you better than either of these two.
Power, Heat and Cooling
Both chips are efficient. In GamersNexus’ all-core Blender test, the 9700X used about 88W and was the most efficient chip on the chart. The 7800X3D came next. In games, 3DCenter’s review roundup (reported by Notebookcheck) put the 7800X3D at about 53W on average.
The “TDP” number is only a rating, not real power use. A TechPowerUp forum user pointed out that the 7800X3D is rated at 120W but uses far less in practice.
On heat, be careful comparing numbers. GamersNexus saw the 9700X at about 50 to 52°C in an all-core Blender run with a 360mm cooler in a 21°C room. GamersNexus also warned that AMD moved the temperature sensors between generations, so readings do not compare directly with older chips. Separately, a Techenclave user said their 7800X3D went above 80°C under full load even with a 360mm cooler in a room around 35°C. Those two numbers come from different tests and rooms, so do not stack them against each other. The simple lesson: neither chip comes with a cooler, so buy a good one.

Can You Make the 9700X Faster?
A little, yes. Do not expect it to catch the 7800X3D in cache-heavy games.
Faster RAM helps the 9700X a bit. In F1 24, GamersNexus saw the AMD Ryzen 9700X gain 5% with DDR5-6400. The 7800X3D did not gain from the faster kit, and it still led by 20.5%. GamersNexus said this fits the idea that a big cache makes a chip less dependent on memory.
The 105W mode is a mixed story. TechPowerUp reported an above-average 15% gain in its results when the power limit was removed. But Guru3D’s headline for its own test said gaming gains in 105W mode were minimal. A Guru3D forum user explained it this way: more power helps heavy multi-core work, and games gain much less. Our take: more power helps work most and games least.
Tuning has fans. One LTT forum member said the 9700X with PBO and Curve Optimizer is a strong gaming CPU. That is an opinion, not a test result.
Motherboard, RAM and Buying Used
Both chips use AM5, so any good AM5 board runs either one. Our best motherboard for Ryzen 7 9800X3D guide works as a board guide here too, because the socket is shared. For memory, see our best RAM for gaming picks.
If you buy a used 7800X3D, one Techenclave user advised getting the bill and warranty, and testing the chip properly. The same thread warned that some ASRock boards need a BIOS update before they run X3D chips safely. That is one user’s warning, so check your board maker’s support page and update the BIOS first.
Which Graphics Card Fits Each Chip?
The same logic applies to your GPU. The stronger your GPU, the more the CPU matters. With a high-end card at 1080p or 1440p high refresh, the 7800X3D keeps the card fed better in CPU-heavy games. With a mid-range card at 1440p or 4K, your GPU is the limit and the two CPUs feel close, as the GamersNexus 1440p results show.

Should You Upgrade?
Own a 7800X3D? Keep it. GamersNexus said that on AM5 there is no reason to upgrade the 9700X over older parts, and that a 7800X3D may make more sense for gaming in many cases.
Own a 9700X and play CPU-heavy games? A 7800X3D would help. A 9800X3D helps more. TechSpot found the 9800X3D about 8% faster than the 7800X3D across 45 games at 1080p with an RTX 4090, and the same 8% in a 12-game retest with an RTX 5090. We compare those two in our 7800X3D vs 9800X3D guide.
Own an older chip? Both are big upgrades. Check stock before you commit, since the 7800X3D can be harder to find in some stores.
Which One Should You Buy?
Buy the 7800X3D if you play at 1080p or 1440p, want high FPS, or play CPU-heavy games like Baldur’s Gate 3, Dragon’s Dogma 2 or F1 24.
Buy the 9700X if you edit video or code often, want a chip that is easy to keep cool, or play mostly GPU-heavy games at 4K.
Look at the 9800X3D if you want the fastest gaming option on AM5.
For most gamers, the 7800X3D wins the 9700X vs 7800X3D debate. For people who do real work on the same PC, the 9700X is a solid, efficient choice.
FAQs About 9700X vs 7800X3D
Was buying the 9700X a mistake for 4K gaming?
An LTT forum user asked this after buying a 9700X for 3440×1440 and 4K gaming with an RTX 4090. One reply said the difference at 4K was single-digit FPS in a video they had seen. Another said X3D chips age better and help more in CPU-heavy games. Our data agrees with both: the lead was about 2% at 4K in MuyComputer’s test, but it grows in CPU-heavy games.
Should I buy a new 9700X or a used 7800X3D?
A Techenclave thread asked this exact question. Replies leaned toward the 7800X3D for gaming, if you get the bill and warranty and test the chip well. One reply also said ASRock boards need a BIOS update before running X3D chips.
Is it smarter to save on the CPU and buy a stronger GPU?
A Reddit r/PcBuildHelp thread weighed a 7800X3D with an RTX 5070 Ti against other builds. One reply said 1440p is mostly GPU limited, so a stronger GPU helps more. Another said the 7800X3D is faster in games, more efficient, and can be upgraded without a new board. Both points are fair. It depends on your games and screen.
Can the 9700X match the 7800X3D if I tune it?
A TechPowerUp forum user said 105W mode gave 5% to 15%, but another user in the same thread doubted it. Guru3D’s headline said gaming gains were minimal. Tuning helps a bit, but GamersNexus still saw a 20%+ gap in cache-heavy games.
Does the 7800X3D run hot?
A Techenclave user reported 80°C and above under full load with a 360mm cooler in a very warm room. That is a worst-case load, not normal gaming. Buy a good cooler for either chip, and check your temps.
Is the 9700X better for work?
In a HardForum thread titled “7800X3D or 9700X – pick your champion,” one user said the 9700X does better in productivity while the 7800X3D gets more frames in games. A commenter noted that 35 of 43 votes went to the 7800X3D. Review data agrees: the 9700X is faster for work, but by how much depends on the task.
Should I skip both and buy the 9800X3D?
In the same LTT thread, a veteran member said they would go 9800X3D because it can be overclocked. TechSpot’s tests show it is about 8% faster than the 7800X3D. Whether that is worth it depends on your GPU, screen and budget.
Final Words
The 9700X vs 7800X3D answer depends on what you do. For gaming, the 7800X3D’s big cache is a real advantage, and it grows in CPU-heavy games and at lower resolutions. For heavy work, the 9700X is faster. At 4K with a strong GPU, either one will do the job.
