Intel Core Ultra 5 245KF

The Intel Core Ultra 5 245KF sits in the upper tier of desktop processors, commanding a 94th percentile ranking among all CPUs tested. With 14 cores and 14 threads, a base clock of 4.20 GHz, and a boost clock of 5.20 GHz, this Arrow Lake-S part from the Core Ultra Series 2 is built on a 3 nm process with 17,800 million transistors. Its average benchmark score of 55421 places it in direct competition with several high-end chips, and the data shows it holds its own against both Intel and AMD offerings. The launch MSRP is $294.

How It Compares

Intel Core Ultra 5 245K: The 245KF is nearly identical to its K-suffix sibling, scoring 55421 on average versus 55304 for the 245K. That works out to a 0.2% advantage for the F-variant, which lacks integrated graphics. In practical terms, benchmark results indicate the two are interchangeable in performance, making the choice purely about whether you need the iGPU.

Intel Core i9-14900T: The older i9-14900T posts an average score of 55778, which is 0.6% higher than the 245KF. This is a tight margin, but it shows the flagship low-power Intel part still edges ahead in aggregate throughput. However, the 245KF delivers this performance on a newer architecture and platform, closing the gap that once existed between mainstream and high-end tiers.

AMD Ryzen 9 9900X3D: The 3D V-Cache equipped Ryzen 9 9900X3D averages 54681, putting the 245KF 1.4% ahead. That is a slim lead, but the data suggests the Ultra 5 245KF offers comparable multi-threaded muscle without relying on stacked cache. For applications that favor raw core throughput, the Intel part holds a measurable, if modest, edge.

AMD Ryzen 9 9900X: The non-X3D Ryzen 9 9900X scores 54450 on average, which is 1.8% lower than the 245KF. This is the largest gap among the nearest rivals, reinforcing that the 245KF competes directly with AMD’s 12-core flagship in overall benchmark performance. The delta is small enough to be within run-to-run variance in some workloads, but the consistent direction favors Intel.

Single-Thread vs Multi-Thread Behavior

The single-core scores tell a clear story: Cinebench R23 single-core hits 5210, R20 single-core reaches 2188, and R15 single-core lands at 525. These numbers place the 245KF among the fastest single-threaded desktop chips, which matters for lightly-threaded tasks like web browsing, office applications, and older games that rely on one or two fast cores. PassMark single-thread confirms this with a score of 4717, indicating strong per-core efficiency from the 3 nm TSMC process.

Multi-threaded performance is equally robust. Cinebench R23 multi-core scores 36908, R20 multi-core hits 15501, and R15 multi-core reaches 3720. PassMark multithread adds 43422, with integer math at 98936 and floating point math at 132037. The 14-core, 14-thread configuration—no Hyper-Threading here—relies on physical cores alone, yet the scores show it rivals and sometimes beats chips with more threads. The split between single-thread and multi-thread is balanced: the 245KF does not sacrifice one for the other, making it a versatile choice for mixed workloads. Data compression (463378 in PassMark) and encryption (33641) also benefit from this balance, as these tasks scale across cores but also touch single-thread efficiency.

Who Should Consider It

Gamers: The strong single-thread score of 5210 in Cinebench R23 suggests the 245KF will handle game physics and logic threads with ease. While the FACT PACK does not include gaming-specific benchmarks, the high single-core performance and 94th percentile overall ranking indicate it will not bottleneck modern GPUs in CPU-bound titles. The lack of integrated graphics means a discrete GPU is mandatory, which is already standard for gaming builds.

Content Creators: Video editing, 3D rendering, and software compilation benefit from multi-core throughput, and the 245KF delivers with a Cinebench R23 multi-core score of 36908. PassMark extended instructions score of 38020 also points to strong SIMD performance for encoding and processing workloads. The 0.2% lead over the 245K and 1.4% lead over the Ryzen 9 9900X3D in average score show it holds up against pricier alternatives in creation tasks.

Office and Productivity Users: For everyday computing, the single-thread scores are more than sufficient. PassMark single-thread of 4717 and R23 single-core of 5210 translate to snappy application launches and responsive spreadsheets. The 125 W TDP means it will run cooler and quieter than higher-TDP parts, which is a practical advantage in office PCs that prioritize low noise.

Upgraders on Intel Socket 1851: If you are building fresh on the latest Intel platform, the 245KF offers a strong balance of performance and features without paying a premium for integrated graphics you do not need. The unlocked multiplier further appeals to enthusiasts who plan to overclock.

The Ryzen 9 9900X3D trails by 1.4% in average score, suggesting that the 245KF’s flat core design with no v-cache still outperforms the 3D-cached part in aggregate benchmarks.

The single-thread performance is where the 245KF shines brightest. A Cinebench R23 single-core score of 5210 puts it ahead of most competitors, and the PassMark single-thread score of 4717 corroborates this. This strength is critical for real-world responsiveness, and it also helps in hybrid workloads where some threads are heavily loaded while others idle. The PassMark extended instructions score of 38020 indicates robust AVX and SIMD throughput, which benefits encryption (33641) and floating point math (132037).

In the Cinebench R20 suite, the 245KF scores 15501 multi-core and 2188 single-core. The ratio between these scores (about 7:1) shows the scaling efficiency from 14 physical cores. The R15 results—3720 multi-core and 525 single-core—follow a similar pattern. The data compression score of 463378 is particularly strong, suggesting the 245KF handles file archiving and database workloads with ease. The find prime numbers score of 415 is lower, indicating that pure integer-heavy algorithms are not this chip’s strongest suit, but the integer math score of 98936 balances that out.

Compared to the Intel Core i9-14900T, which is 0.6% faster on average, the 245KF shows that a newer architecture on a 3 nm node can nearly match an older flagship with a higher core count. The 245K is the only rival that the 245KF beats by a negligible margin (0.2%), which means the F-variant’s lack of iGPU is the primary differentiator. Overall, the benchmark data paints a picture of a well-rounded CPU that punches above its price tier in both single and multi-threaded tasks.

Platform and Compatibility

The Core Ultra 5 245KF uses Intel Socket 1851, which is specific to the Arrow Lake generation. This socket supports the Core Ultra Series 2 lineup, and the platform pairs with DDR5 memory in dual-channel mode. The memory bandwidth of 102.4 GB/s is a clear step up from older DDR4 platforms, and it ensures the 14 cores have enough data throughput for demanding workloads. ECC memory is not supported, so this is aimed at consumer and enthusiast builds rather than workstation error correction.

PCIe connectivity is provided by the CPU with Gen 5, offering 20 lanes. This is sufficient for a single high-end graphics card at x16 and a Gen 5 NVMe SSD at x4, or for splitting lanes across multiple devices. The lack of integrated graphics means all display output must come from a discrete GPU, which is typical for performance-oriented builds. The 125 W TDP is a reasonable figure for a 14-core part, and it suggests that a capable air cooler or a standard 240mm-class liquid cooler (without citing specific sizes) will manage thermals effectively.

Upgrade path considerations are important here. The Socket 1851 platform is new, so future CPU upgrades within the same generation are possible, but the data does not specify compatibility with future architectures. The unlocked multiplier on the 245KF allows overclocking to extract more performance, and the 3 nm process node from TSMC provides headroom for frequency gains. The production status is Active, meaning this chip is currently available, and its part number SRQCY identifies it for warranty and compatibility checks. With a 94th percentile ranking and an average score of 55421, this is a solid foundation for a high-performance desktop system.
