For an AM4 gaming PC, start by comparing the Ryzen 7 5700X3D with the Ryzen 7 5800X3D; the 5700X3D is a strong gaming-focused upgrade candidate, while the 5800X3D makes sense when its price and availability are favorable. For rendering, encoding, or other well-threaded work, compare the Ryzen 9 5900X and 5950X instead. Before buying any of them, verify support for your exact motherboard and BIOS version, and account for cooling and total platform cost.
Which AM4 processor fits your upgrade?
The right choice depends on what limits your current PC. Game performance varies by title, graphics card, resolution, and system configuration, so no single CPU guarantees a particular frame-rate gain. Likewise, more cores can help some well-threaded applications without making a processor the best choice for every creative workload.
| Upgrade priority | Processors to compare | Why |
|---|---|---|
| Gaming | Ryzen 7 5700X3D and Ryzen 7 5800X3D | Both are AM4 X3D options. Current PC Gamer guidance names the 5700X3D as its AM4 upgrade pick and describes performance as close to the 5800X3D; individual game results vary. PC Gamer’s 2026 gaming CPU guide and Tom’s Hardware’s 5700X3D review discuss the gaming-focused case. |
| Heavily threaded productivity | Ryzen 9 5900X and Ryzen 9 5950X | The 12-core 5900X and 16-core 5950X are worth comparing when the application can use additional CPU cores. Check benchmarks for the software and work you actually do; the available reviews do not establish results for every application. Tom’s Hardware’s 5700X3D review discusses its gaming-versus-productivity trade-off. |
Ryzen 7 5700X3D: the gaming-focused shortlist pick
The 5700X3D is a sensible first CPU to compare for an existing AM4 gaming system. PC Gamer’s 2026 guidance names it as its AM4 upgrade pick, while Tom’s Hardware’s review presents it as a gaming-oriented upgrade and notes that it is less compelling for productivity than for gaming. Whether it is the right buy still depends on your board support, cooler, local price, and availability.
Tom’s Hardware lists the 5700X3D in its review specifications as an 8-core, 16-thread processor with a 3.0 GHz base clock, up to 4.1 GHz boost, 100 MB combined L2/L3 cache, and 105 W TDP. These are the review’s specifications, not a statement about current stock or pricing. The same review lists the 5800X3D’s base and boost clocks as 3.4 GHz and 4.5 GHz, respectively. See the review and its test context.
#1 Best Overall
- Powerful Content Creation and Game Performance
- 16 Cores and 32 processing threads, based on AMD "Zen 3" architecture
- 4.8 GHz Max Boost, unlocked for overclocking, 72 MB cache, DDR4-3200 support
- For the AMD Socket AM4 platform, with PCIe 4.0 support
- Cooler not included
Ryzen 7 5800X3D: an alternative when the deal is right
The 5800X3D is an 8-core, 16-thread Zen 3 processor for AM4. AMD specifies up to 4.5 GHz boost, 96 MB of L3 cache, a 105 W default TDP, and an April 20, 2022 launch date. Its listed supporting chipset families include X570, X470, B550, B450, and A520, but that list does not confirm compatibility with every board in those families. The exact motherboard CPU support page is decisive. AMD’s 5800X3D specifications also state that no thermal solution is included.
Compare its current local price and availability with the 5700X3D before choosing. The sources cited here do not establish a current street price for the 5800X3D, and older review-era prices should not be treated as current quotes.
Rank #2
- Can deliver fast 100 plus FPS performance in the world's most popular games, discrete graphics card required
- 6 Cores and 12 processing threads, bundled with the AMD Wraith Stealth cooler
- 4.2 GHz Max Boost, unlocked for overclocking, 19 MB cache, DDR4-3200 support
- For the advanced Socket AM4 platform
Ryzen 9 5900X or 5950X: consider them for threaded work
If your priority is software that benefits from many CPU cores—such as certain rendering or encoding workloads—compare the Ryzen 9 5900X (12 cores) and 5950X (16 cores) with the X3D gaming options. Extra cores do not automatically improve games or every creative task. Look for benchmarks using your application, settings, and type of project; broad product labels are not enough to predict your result.

Check motherboard support and cooling before ordering
- Identify the exact board. Record the motherboard model and, where the manufacturer distinguishes them, its hardware revision.
- Find the CPU support entry. On the manufacturer’s support site, locate that exact model and revision, then check the target processor and the minimum BIOS version. ASRock’s AM4 CPU support list illustrates why a vendor-specific lookup matters; it is not a universal compatibility list.
- Update the BIOS if required. If the board needs a newer BIOS, follow the manufacturer’s update procedure while the existing processor is still installed, if the board requires a supported CPU to perform the update. Do not assume that an AM4 socket alone guarantees support.
- Assess the cooler and case. AMD says the 5800X3D has no included thermal solution and recommends liquid cooling for optimal performance. That recommendation does not establish that every owner must replace a cooler. Consider the specific CPU, cooler capability, case fit, and airflow before deciding.
- After installation, check operation. Confirm the system starts reliably and monitor temperatures and stability during ordinary use.
- Compare total upgrade cost. Set the CPU-only upgrade cost against a platform change, including any motherboard and memory you would need. Use current local prices and account for the components you can keep.
How to interpret AMD’s gaming claim
In its March 15, 2022 announcement, AMD said processors with stacked cache technology offered 15% more gaming performance versus processors without stacked cache technology. That is AMD’s attributed comparison, not a universal independent benchmark or a promise of a 15% uplift in your games or system. AMD’s announcement also quoted Saeid Moshkelani, then senior vice president and general manager of its Client business unit: “With today’s announcement AMD is offering users the power of choice by bringing leadership gaming performance to all levels of system builds.” Read AMD’s March 15, 2022 announcement.
