Does the Ryzen 7 7800X3D match your needs with the RTX 4070?
Does the Ryzen 7 7800X3D match your needs with the RTX 4070?
Good morning everyone, here’s what I’m sharing: I just bought an ASUS Dual GeForce® RTX 4070 OC Edition with 12GB GDDR6X memory. I’m trying to decide which processor to install—either the i7-13700K or the Ryzen 7 7800x3d, or the i5-13600K or the Ryzen 7 5800x3d. I want to see if there’s a noticeable difference between these options and the other pair. I’m also curious about which CPU would work best with this GPU. I hope I won’t run into bottlenecks, but I’m worried that the i7-13700K and Ryzen 7 7800x3d might be too much for this card. Could there be another good choice within my budget? My max budget is $399, and the Ryzen 7 7800x3d is already at that price, so I can’t afford something more expensive. But if there’s a better alternative at a lower cost, I’m open to it. 😀
I plan to mainly use the PC for gaming at 1440p, switching to 1080p to keep 240fps on some competitive games.
Thanks in advance.
If you aim for 240 fps or above, it’s best to opt for one of the first two options mentioned. Their greater number of cores, enhanced onboard Smart and level 2 cache (especially for Intel models, but probably also for AMD), and increased maximum clock speed will clearly show in performance. This improvement comes from more cores and better caching, which together boost overall processing even if the game isn’t perfectly optimized for high thread usage.
For the quickest gaming experience, choose a Ryzen X3D chip. If you can handle the costs, don't be concerned about it being too powerful—just ensure it meets your desired performance without breaking the bank.

Their greater number of cores, onboard Smart and level 2 cache (especially for Intel models, though likely also for AMD), and higher maximum clock speed will clearly show better performance compared to anything that can take advantage of these features. Whether a game is well-optimized for high thread counts or not, the increased single-core speed will still matter.
You're correct that a bottleneck is unlikely with these choices. Among the models you mentioned, selecting one of the top-tier options would be even more beneficial for achieving high frame rates and preserving CPU longevity. Still, it won’t cause major issues if you pick from the other two available. If your budget permits, the 13700k stands out due to its superior single and multi-core performance relative to the 7800x3d, especially according to Passmark scores. However, some titles may perform better with the architecture of x3d models in gaming contexts, though this isn’t guaranteed for all games.
Displays AI performance as similarly lacking as Reddit posters who simply regurgitate random information they've picked up elsewhere without understanding.
In most games, you'll experience GPU limitations when running at 1440.
A 7900x3d setup is usually a poor choice overall; you still face the issue of only half the cores utilizing the 3D cache memory. The 7800x3d offers a better balance.
With very few exceptions, the 13900k doesn't give an edge over the 13700k, and most games aren't heavily CPU-bound.
It's difficult to judge between a 13700k and a 7800x3d. Generally, the 7800x3d performs better in games, but if you plan additional tasks for the machine, the 13700k might still be worth considering.
Here’s a revised version of your text:
I tend to favor air coolers for CPU cooling since they offer better value, reliability, and often better performance than AIO units. The Thermalright Peerless Assassin stands out as an excellent air cooler, particularly given its low cost.
For my motherboard, I selected the MSI MAG Z790 Tomahawk. It’s budget-friendly and reliable, featuring a generous number of USB ports, support for up to 128 gigabytes of RAM, and ample on-board expansion options—making it a solid choice at its price point.
Current high-capacity DDR4 kits are reasonably priced, so I opted for the G.Skill Trident Z 3600 CL16 2x16 package. It delivers strong performance at 3600 MHz and offers low First Word latency to maximize speed.
Samsung has long been a leader in SSD technology, so I picked the Samsung 970 Evo Plus 1TB for Windows, paired with an additional 2TB from Seagate for gaming needs. You can easily replace the hard drive with a faster model like the Samsung 870 Evo if desired. The same applies to the 970 Evo Plus. The 980 Pro is roughly $30 more, but it won’t significantly increase your budget if you’re after the fastest SSD available.
When choosing a case, personal preference matters. I went with the Corsiar iCUE 4000D Airflow. If you prefer a different look or texture, the Corsair iCue 4000X with glass is an alternative. Corsair also produces cases with ample internal space.
For power supply, the Corsair RM 1000x should suffice. The 4070 can operate on an 850-watt PSU, but depending on your CPU choice, I wouldn’t suggest going that low. This leaves you with about $100 remaining for a monitor. There are great options available for around $200 from Acer if you’re open to buying refurbished units. I’ll include a link here if you’d like more details.
I hope this helps, and take care.
And I concur mostly. It's essentially a "tossup" when deciding which option offers superior performance, because for almost every type of hardware—especially CPUs and GPUs—it changes depending on the game. Certain titles use particular instruction sets or APs that perform better with one processor or one graphics card than another.
However, overall Passmark ratings remain quite reliable for general performance, as they consider a wide range of factors to assign a score. They don't excel at measuring strictly gaming performance, but if something meets measurable benchmarks and performs better than alternatives, it usually does well in games too.
In comparison, most reviews of specific CPUs focus on lab conditions, meaning the machines are clean and only have essential software installed. This makes the scores less representative of real-world usage, since people rarely run just Windows and the necessary game files.
So for anything that isn't a gaming benchmark, even if it might score higher in a controlled setting, it's probably not useful when discussing a system that likely has many other applications running alongside the game. In such cases, the Intel CPU may still be the stronger choice because it optimizes better and frees up resources for the game engine.
But again, we're probably debating this a bit too much, as performance differences are generally minor. The cheaper option is often the more sensible one.
Thank you for your inquiry. I’ve considered the changes and decided to buy a Ryzen 7 7800X3D. I wanted to know what adjustments could be made to the build. I’ve observed that the processor only supports DDR5, yet it uses less power than the i7-13700. I’m asking: 1) Is it possible to use a slightly lower wattage PSU? 2) What DDR5 RAM would you suggest? 3) Since it tends to run hotter than the i7-13700k, would the cooling system still fit? Thank you in advance for your help.
You’ll need a distinct motherboard and a DDR5 kit. For the motherboard, MSI offers a Tomahawk model designed for AMD systems, such as the MSI MAG Tomahawk B660. This unit supports DDR5, WiFi 6E, and PCIe Gen 5, making it a strong option. Your RAM selection is crucial, especially compared to Intel setups. A poor memory transfer can greatly limit Ryzen performance due to high latency. You should aim for a kit with a First Word latency of ten milliseconds or less to get the best results with Ryzen 7000 chips. The G.Skill Trident Z5 Neo 6000 CL30 2x16 kit fits this need, offering a speed of 6000 with a low CAS latency of 30 and meeting the ten-millisecond benchmark. Additionally, it carries AMD Expo certification, ensuring it’s optimized for AMD hardware for peak performance and compatibility.
For power needs, I recommend sticking with a 1000 watt PSU. Would you consider using something lower? Not really, since AMD components consume less power than Intel ones. My RTX 2080 calls for at least a 650-watt unit, and I’ve run an original 650-watt Corsair PSU without any issues over the past five years. Using a lower wattage could be risky as power supplies lose efficiency with age, potentially reducing output over time. A 1000-watt unit provides more headroom for future upgrades like additional SSDs, fans, RGB components, and ensures longer runtime. The RTX 4090 is also prone to random power spikes under load; a higher wattage prevents unexpected shutdowns during intense gaming or rendering.
The Peerless Assassin cooler will likely keep you comfortable even with high-temperature chips like the 7800X3D. If you want to maximize your CPU’s cooling, consider upgrading to a cooler that maintains optimal temperatures. For that, I suggest looking at the Noctua NH-D15 Black, which offers excellent cooling performance and stays within budget, though it may increase the overall build cost slightly.
Here’s the revised list featuring the updated CPU, motherboard, and RAM. I hope this clarifies things and helps you proceed.
It wouldn't make sense for a CPU that consumes less power to become hotter. All the electricity is transformed into heat while it operates. I believe the 7800x3d offers around a 100 watt difference, which is quite notable. It's uncertain if the 13700k model could overheat and consume excessive power when you enable the power cap removal option. The 7800x3d generally doesn't allow significant overclocking in AMD systems.
This could open up options for using a different cooling solution. There are many air coolers available that have been tested on this site, typically using 13700k units. I recommend reviewing those guides for advice. Your cooler selection depends less on its cooling capacity and more on factors like fan noise and fit within your case.
I think most air coolers on the list should work well with a 7800x3d, and your decision will mainly hinge on fan colors and LED lighting preferences.
Don't reduce your PSU size; it might be necessary later when upgrading the graphics card. You should be able to swap it for a newer "50" series card in a few years, and your CPU will still perform adequately.
