In 2025, the CPU market is both stable and dynamic: in the desktop segment, architectural ideas proven effective for gaming (large caches, like 3D V-Cache) are solidifying, while in the server segment, the race for performance per watt (perf/W) and lower TCO is leading to a significant re-evaluation of platforms and ecosystems. Concurrently, support for DDR5, PCIe 5.0, and CXL is expanding, and in data centers, interest in ARM solutions like NVIDIA Grace for HPC/AI workloads is growing. In this article, we’ve compiled the best CPUs of 2025 across two key areas – desktop (gaming and content creation) and servers – and aligned the choices with real-world tasks that can be solved using Unihost infrastructure.
How We Chose: Evaluation Criteria
To make our recommendations practical, we relied on three groups of criteria:
- Performance in gaming and multimedia applications. For 1080p/1440p gaming, latency and caches are critical; for content, scaling by cores/threads and memory subsystem speed are key.
- Economics and ecosystem. Platform cost (motherboard, memory, cooling), availability and stability of microcode, maturity of software and drivers.
- For servers – perf/W, scalability, PCIe 5.0/CXL support, memory (volume/channels), total cost of ownership (TCO) for specific workloads (databases, streaming, AI/ML, blockchain nodes).
Desktop: Best CPUs for Gaming in 2025
From a pure gaming perspective at 1080p, Tom’s Hardware calls the AMD Ryzen 7 9800X3D the fastest gaming chip of 2025 – its lead over competitors in several titles reaches double-digit percentages thanks to its large 3D V-Cache and favorable latency profile. This processor consistently outperforms not only previous generations but also current Intel tops, including the Core Ultra 9 285K and the former Core i9-14900K, in typical gaming scenarios under equal testing conditions.
Why is 3D V-Cache so important? Many modern game engines are sensitive to latency and L3 cache size, especially in scenes with a high number of data accesses, AI agents, and complex physics. An additional cache layer allows for more frequent “hits” in fast memory levels and reduces accesses to RAM, which ultimately translates into higher FPS and smoother frame times. This is a case where an architectural focus on cache provides a real advantage without an extreme increase in power consumption
Alternatives and reasonable compromises. If you’re building a universal system for gaming and light editing/streaming, options with more affordable Ryzen 7/5 of the latest generations or comparable Core Ultra i7/i5 are possible. However, if the priority is FPS in competitive titles, the 9800X3D provides a “long-term” advantage due to its cache. If you stream and encode simultaneously, it makes sense to consider models with more cores (see the next section on content), or combine the CPU with a powerful GPU and a configured hardware encoder.
Desktop: For Content Creation (and Hybrid “Gaming + Production”)
For content creation tasks – rendering, 3D scenes, compositing, video encoding – the key role is played by scaling by cores/threads, memory bandwidth, and the presence of “wide” interfaces (PCIe for fast SSDs, capture cards, accelerators). In 2025, several specialized publications note that the top Ryzen 9s with 3D V-Cache remain extremely strong all-rounders: they are great in games and very competitive in multi-core tasks, especially where cache and memory play a significant role.
If you’re editing 4K/8K, actively using effects and plugins, and storing large media pools on NVMe, pay attention to:
- the number of PCIe lanes (for multiple SSDs, accelerators/expansion cards);
- the volume and speed of DDR5 (for complex timelines and advanced codecs);
- frequency stability under prolonged loads (cooling, power limits).
The “universal flagship” approach will give you fewer compromises: strong gaming plus predictable performance in work tasks. If the budget is limited, it’s wise to aim for the “sweet spots” of the generations – where the price/performance is close to optimal, and the platform remains relevant in terms of interfaces.
Server CPUs 2025: EPYC, Xeon 6, and NVIDIA Grace
In data centers in 2025, the confrontation between x86 platforms with a focus on perf/W and TCO continues, and the share of ARM solutions in HPC/AI niches is growing. In the x86 segment, AMD EPYC (generations 9004 “Genoa” and 9005, also known as “Turin”) is widely perceived as the leader in multi-threaded performance and energy efficiency, which together provides an advantage in computing density and cost of ownership for typical cloud and corporate workloads.
Intel Xeon 6 responds with a strong ecosystem, developed compatibility, and a balanced set of I/O: current support for PCIe 5.0 and CXL is important for high-speed NVMe arrays and scalable memory/accelerator configurations. The choice of Xeon 6 may be justified where integration with existing stacks, specific extensions, and software validations is critical, as well as when certain I/O requirements are a priority.
ARM in servers, primarily NVIDIA Grace based on Neoverse V2, is strengthening its position in HPC/AI thanks to high energy efficiency and scalability. For computing clusters dominated by container workloads, the Python stack, microservices, and modern compilers, the ARM platform looks increasingly attractive. However, when migrating old binaries and specialized software, it’s important to check compatibility in advance.
Where which CPU is appropriate:
- Databases and high-load web services: EPYC is famous for its number of cores, memory channels, and perf/W – an excellent choice for OLTP/OLAP and scaling across nodes.
- Streaming and CDN: network capabilities, I/O, and predictability under constant load are important – we look at EPYC and Xeon 6, depending on the infrastructure and SLA.
- AI/ML inference and HPC: with a strong focus on GPU accelerators, a CPU with sufficient PCIe 5.0 and CXL supply is chosen; Grace is interesting in specialized tasks with a focus on energy efficiency and integration with the NVIDIA ecosystem.
- Blockchain/nodes: perf/W, stability, network, disks are critical. Multi-core EPYCs with good energy economy and security options are a common choice, but Xeon 6 is also possible depending on software requirements and budget.
How to Match CPU Choice with Unihost Products

Choice Checklist
- Desktop for gaming: if the priority is FPS/frame time, focus on models with a large cache (e.g., Ryzen 7 9800X3D) and don’t forget about the combination with a GPU and RAM.
- Desktop for content: count cores/threads, memory bandwidth, PCIe lanes for storage and accelerators.
- Server: describe the workload – databases, streaming, AI/ML, nodes – and compare perf/W, I/O, memory, TCO over the ownership horizon. EPYC is a frequent leader in multi-threading and energy efficiency, Xeon 6 has a strong ecosystem and I/O, ARM (Grace) has prospects in HPC/AI.
