The Intel Core Ultra 7 265F is a 20-core, 20-thread desktop processor from the Core Ultra Series 2, built on the Arrow Lake architecture and a 3 nm TSMC process. It operates at a 2.40 GHz base clock and 5.30 GHz boost, with 30 MB of shared L3 cache and dual-channel DDR5 memory support. The chip occupies the 95th percentile among all CPUs in the database, with an average benchmark score of 62,876.

Benchmark Performance

The Core Ultra 7 265F delivers a Cinebench R23 multi-core score of 41,051 and a single-core score of 5,795. In Cinebench R20, it reaches 17,241 multi-core and 2,433 single-core, while R15 results show 4,137 multi-core and 583 single-core. PassMark tests reinforce this profile: multithread score of 48,349, single-thread score of 4,717, integer math at 137,936, floating-point math at 172,749, and data compression at 489,271.

Against its nearest rivals, the 265F’s average score of 62,876 sits 0.7% above the AMD Ryzen 9 7950X3D (62,443) and 0.9% above the Intel Core i9-13900K (62,314). It trails the Intel Core i7-13790F by 0.7% (63,348) and the Intel Core i9-13900KS by 1.7% (63,990). These deltas are narrow, placing the 265F in the same performance tier as those flagship parts. The Cinebench R23 single-core result of 5,795 is notably high, suggesting strong per-thread performance that benefits lightly threaded workloads. Multi-core scaling is also robust, as the 20 threads produce a 41,051 R23 score that competes directly with 24-thread rivals.

Who Should Consider It

Gamers will appreciate the single-thread performance. The 5,795 R23 single-core score and 4,717 PassMark single-thread figure indicate snappy responsiveness in game logic and physics simulation, while the 20 cores handle background tasks without stutter. Content creators handling video encoding, 3D rendering, or large dataset compilation can leverage the 41,051 R23 multi-core score and 48,349 PassMark multithread result. The floating-point math score of 172,749 suggests strong scientific and engineering compute, while the integer math score of 137,936 supports general productivity. For office workloads, the data compression score of 489,271 and random string sorting of 60,446 point to efficient file handling and database operations. The 265F also handles encryption well with a PassMark encryption score of 38,399, making it suitable for secure communications and VPN tasks.

How It Compares

AMD Ryzen 9 7950X3D: The 265F holds a 0.7% higher average benchmark score than the 7950X3D (62,876 vs. 62,443). This margin is tiny, but it indicates the Intel part edges ahead in aggregate performance. The 7950X3D’s 3D V-Cache is not reflected in these scores, so the comparison is purely on the tested workloads.

Intel Core i7-13790F: The 13790F leads by 0.7% (63,348 vs. 62,876). The 265F’s 20 cores and 20 threads are fewer than the 13790F’s 16 cores and 24 threads, yet the newer Arrow Lake architecture narrows the gap to a sub-1% deficit. This suggests the 265F’s per-core efficiency compensates for its lower thread count.

Intel Core i9-13900K: The 265F is 0.9% ahead of the 13900K (62,876 vs. 62,314). Despite the 13900K having more threads (24 vs. 20), the 265F’s higher single-core and competitive multi-core scores tip the aggregate in its favor.

Intel Core i9-13900KS: The 13900KS outperforms the 265F by 1.7% (63,990 vs. 62,876). This is the largest delta among the rivals, reflecting the KS’s higher boost capabilities. Still, the 265F remains within 2% of a chip that is often considered the top of its generation.

Platform and Compatibility

The Intel Core Ultra 7 265F is built for the Intel Socket 1851 platform, which is the mounting interface for Arrow Lake-S desktop processors. It supports dual-channel DDR5 memory with a peak bandwidth of 102.4 GB/s. The CPU provides 20 PCIe Gen 5 lanes (CPU only), enabling high-speed connectivity for graphics cards and NVMe storage. There is no integrated graphics, so a discrete GPU is required for display output. The processor was released on January 6, 2025, and is currently in active production. Its part number is SRQCV. The platform does not support ECC memory, which is typical for consumer desktop chips.

Single-Thread vs Multi-Thread Behavior

The 265F exhibits a clear split between single-thread and multi-thread performance. In Cinebench R23, the single-core score is 5,795, while the multi-core score reaches 41,051—a ratio of approximately 7.1:1. PassMark shows a similar pattern: single-thread at 4,717 and multithread at 48,349, a ratio of about 10.3:1. This indicates that the processor scales well across its 20 threads, making it effective for parallel workloads like rendering, encoding, and scientific simulation. The high single-thread scores also ensure that tasks which rely on one or two cores—such as legacy applications, certain game engines, and interactive tools—run with low latency. The base clock of 2.40 GHz and boost of 5.30 GHz provide a wide dynamic range, allowing the chip to idle efficiently and burst to high frequencies when needed.

Power and Thermals

The Core Ultra 7 265F has a TDP of 65 W, classifying it as a mainstream power envelope. This is a modest figure for a 20-core processor, and the 3 nm TSMC process node contributes to its efficiency. The low TDP implies that a capable air cooler or a compact liquid cooler can manage thermals without excessive noise. The 17,800 million transistors on a 243 mm² die suggest a dense design that balances performance and power consumption. For users building a system with power constraints or smaller chassis, the 65 W TDP is a favorable characteristic, though actual power draw can exceed TDP under sustained boosts, as is common with modern CPUs.
