There is no reliable universal PC hardware requirement for emulating PS5 games. The available performance reports cover a few specific games, emulator builds, and test systems; they do not establish a minimum or recommended CPU, GPU, RAM, VRAM, or storage capacity. Check the current compatibility information for the exact game before buying parts: a faster PC cannot make an emulator feature work if that feature is not implemented.
Why there is no dependable PS5 emulator spec
KytyPS5 describes itself as “a free and open-source PlayStation 5 emulator written in C++ for Windows and Linux, with experimental macOS support.” Its project documentation says it can boot 2D games and a selection of 3D games, including titles made with Unreal Engine 4 or 5, Unity, and custom engines. Windows and Linux are its primary tested platforms; macOS support is experimental. The project remains in active development, and its documentation warns that behavior can change significantly between builds.
Those facts matter more than a comparison between a PC’s parts and a PS5’s parts. An emulator has to reproduce console behavior in software, and compatibility can be incomplete or change from one build to another. The project’s stated development priorities include expanding game compatibility and improving boot reliability. A powerful CPU or GPU may provide headroom when a title already runs, but it cannot compensate for missing compatibility.
Current coverage also cautions against treating a successful boot as a promise of a good playing experience. GamesRadar+ reported bugs, visual glitches, and performance problems, including in games that start. “Boots,” “reaches gameplay,” “playable,” and “stable” describe different outcomes.

What the reported PC tests do—and do not—show
The figures below are individual demonstrations or tests reported by Tom’s Hardware in September 2026. They are not controlled comparisons across systems, and none establishes what every PS5 game needs.
| Game and report | Reported test hardware | Reported result and qualification |
|---|---|---|
| Demon’s Souls Remake, 28 September 2026 | NVIDIA RTX 5090; Intel Core i9-14900K | 40–50 FPS in a short KytyPS5 demonstration, with apparently accurate graphics. The same report said gameplay had been reported at 1–2 FPS three weeks earlier, illustrating how quickly a result can change. |
| PS5 version of GTA V, 6 September 2026 | AMD Ryzen 7 9950X3D; Radeon RX 7900 XT | Roughly 40–60 FPS during the starting mission; the run later crashed. |
| PAC-MAN WORLD Re-PAC, 6 September 2026 | AMD Ryzen 7 7700X; Radeon RX 6700 XT | Reported at 60 FPS in that test. The result applies to that game and test, not to PS5 emulation generally. |
The Demon’s Souls figures are especially poor grounds for picking a build to buy: the much higher reported result came only weeks after a report of 1–2 FPS, and it is tied to a short demonstration on a specific emulator build and system. The GTA V result likewise combines a strong frame-rate segment with a later crash. Neither a frame rate nor a boot alone says whether a game remains playable and stable over a full session.
Rank #2
- 5-in-1 Connectivity: Equipped with a 4K HDMI port, a 5 Gbps USB-C data port, two 5 Gbps USB-A ports, and a USB C 100W PD-IN port. Note: The USB C 100W PD-IN port supports only charging and does not support data transfer devices such as headphones or speakers.
- Powerful Pass-Through Charging: Supports up to 85W pass-through charging so you can power up your laptop while you use the hub. Note: Pass-through charging requires a charger (not included). Note: To achieve full power for iPad, we recommend using a 45W wall charger.
- Transfer Files in Seconds: Move files to and from your laptop at speeds of up to 5 Gbps via the USB-C and USB-A data ports. Note: The USB C 5Gbps Data port does not support video output.
- HD Display: Connect to the HDMI port to stream or mirror content to an external monitor in resolutions of up to 4K@30Hz. Note: The USB-C ports do not support video output.
- What You Get: Anker 332 USB-C Hub (5-in-1), welcome guide, our worry-free 18-month warranty, and friendly customer service.
The project documentation does not provide standard gaming-PC requirements, and these reports do not establish general CPU, GPU, memory, or storage thresholds. They also do not show controlled scaling tests that would tell you how much performance a particular upgrade adds.
How to check whether your PC is worth upgrading for one game
- Find the exact game in KytyPS5’s current community compatibility list. Check the emulator build named in the report; compatibility information can become outdated as builds change.
- Read the reported outcome carefully. Determine whether the game merely boots, reaches gameplay, or is described as playable. Look for visual faults, crashes, and other stability problems rather than relying on a frame-rate figure alone.
- Compare like with like. Note the game, emulator build, CPU, GPU, reported frame rate, visual issues, and whether the test crashed. A result for one title or build is not a benchmark for another.
- Upgrade only when there is evidence relevant to your target game. A reported performance limit might make hardware headroom relevant, but an unimplemented compatibility feature is not fixed by buying a faster component.
If no current report exists for your game, the available evidence cannot tell you what PC configuration will make it playable. In that case, buying parts on the assumption that a high-end system will solve the problem is a gamble, not a specification-based upgrade.

Check for a native PC release separately
If your goal is simply to play a particular game on PC, first check whether it has an official PC version. Sony’s PlayStation PC support page lists title-specific CPU, GPU, memory, storage, and performance targets for supported PC releases. Those requirements apply to the named PC version, not to emulating that game’s PS5 version.
