CPU market statistics matter more than ever in 2026 because the CPU is no longer “just” a processor. Modern CPUs are now shipped alongside dedicated AI accelerators (NPUs), bigger on-chip graphics, and increasingly diverse architectures (x86, Arm, and emerging RISC-V in some segments).
This report rounds up the latest CPU market statistics across market size, PC shipment volume (a key demand driver), and the newest x86 vendor share data (desktop, laptop, and server).

CPU Market Size & Growth
Most public “CPU market” sizing is packaged under the broader microprocessor market (which includes CPUs, GPUs, and other processor types). The newest published estimates point to continued expansion driven by AI workloads, edge computing, and data-center buildouts.

Within that broader market, CPUs represented 51.85% share in 2025, while x86 held 45.95% share by architecture (with Arm and RISC-V competing strongly in specific pockets).
PC Shipments (A Major CPU Demand Driver)
Client CPU volume is tightly linked to the PC market. Shipments rose meaningfully in 2025, helped by upgrade cycles and inventory moves by vendors (with Windows 10 support ending on October 14, 2025).

Top PC vendors by shipments (2025)
Large OEM concentration matters because CPU vendors win (or lose) share through design wins across these high-volume channels.
| Company | 2025 Shipments | 2025 Market Share |
|---|---|---|
| Lenovo | 70.8M | 24.9% |
| HP Inc. | 57.5M | 20.2% |
| Dell Technologies | 41.1M | 14.4% |
| Apple | 25.6M | 9.0% |
| Asus | 20.5M | 7.2% |
x86 CPU Market Share Statistics (Q4 2025)
The most widely-cited “CPU market share” dataset in the PC ecosystem is x86 share by unit shipments and revenue share (desktop, mobile, and servers). The newest quarterly figures show AMD expanding across every major category, while Intel remains the volume leader.
Overall x86 CPU unit share (Q4 2025)
| Label | Bar | Value | ||
|---|---|---|---|---|
| Intel |

Max = 70.80%. Widths: Intel 100.00%, AMD 41.24%.
Revenue share (overall x86, Q4 2025): AMD captured 35.4% of x86 CPU revenue share (implying Intel at 64.6%).
Desktop x86 CPU unit share (Q4 2025)

Server revenue share (Q4 2025): AMD reached 41.3% (Intel: 58.7%).
Architecture Shifts: Arm Macs and AI PCs
Arm-based PCs are already material at the platform level because Apple’s Mac lineup is Arm-based. With 25.6M Macs shipped out of 284.7M total PCs in 2025, Macs alone represented about 8.99% of worldwide PC shipments (a practical “floor” for Arm PC share, before counting Windows-on-Arm systems).
At the same time, “AI PCs” are becoming a major CPU platform battleground. Gartner projected AI PCs would represent 31% of the worldwide PC market by the end of 2025 and reach 54.7% share in 2026 (with AI PC units projected at 77.792M in 2025 and 143.113M in 2026).
Key Takeaways
- Market growth is being pulled by AI: CPU platforms increasingly compete on on-device AI performance, memory bandwidth, and performance-per-watt.
- PC shipments rebounded in 2025: higher volume supports client CPU demand, but pricing pressure and component constraints can still reshape mix.
- x86 share is shifting inside segments: AMD’s biggest relative strength in Q4 2025 showed up in desktop and server revenue share, even while Intel led unit volumes across categories.
- Servers remain the profit pool: server CPU revenue share can move faster than unit share due to premium mix and platform attach.
- Arm presence in PCs is already visible: Macs alone were ~9% of worldwide PC shipments in 2025, before counting any Windows-on-Arm growth.
