Intel Core i9-12900F vs Intel Core Ultra 7 265T Comparison

The Intel Core Ultra 7 265T and Intel Core i9-12900F represent two distinct philosophies in Intel’s desktop lineup: the former is a low-power Arrow Lake part with a 35W TDP, while the latter is a high-core-count Alder Lake processor with a 65W TDP. Benchmark results show a clear split, with the Ultra 7 265T winning 14 of 17 head-to-head tests, but the i9-12900F taking decisive victories in specific workloads that reveal its strengths.

Head-to-Head Benchmarks

The most lopsided result in this comparison comes from the PassMark find prime numbers test, where the Ultra 7 265T scores 322 against the i9-12900F’s 127 — a staggering 153.5% advantage. This is a pure mathematical workload, and the Arrow Lake chip’s performance here is exceptional. Similarly, in floating point math, the Ultra 7 265T posts 129,817 versus 96,452 for the i9-12900F, a 34.6% lead. The physics test also favors the newer chip, with 2,391 points versus 1,842, a 29.8% margin.

The Ultra 7 265T’s consistency shows across every Cinebench iteration. In R15 multicore, it scores 3,180 against 3,064 (3.8% faster); in R20 multicore, 13,254 versus 12,770 (3.8%); and in R23 multicore, 31,558 versus 30,405 (3.8%). Single-core results mirror this pattern: R15 single-core yields 449 versus 432 (3.9%), R20 single-core 1,871 versus 1,802 (3.8%), and R23 single-core 4,455 versus 4,292 (3.8%). The uniform delta across all three Cinebench versions suggests a consistent architectural efficiency advantage rather than a workload-specific quirk.

The i9-12900F’s wins are concentrated in three PassMark tests, and they are substantial. Data compression shows the i9-12900F at 451,402 versus 370,158, an 18% advantage. Integer math follows a similar pattern, with 129,504 against 104,943, a 19% lead. Random string sorting also goes to the i9-12900F, scoring 48,477 versus 44,400, an 8.4% margin. These are memory-latency-sensitive and integer-heavy tasks where the older chip’s hybrid architecture with 24 threads appears to provide an edge.

Other notable wins for the Ultra 7 265T include data encryption (29,687 versus 25,251, a 17.6% lead), extended instructions (28,609 versus 28,265, a slim 1.2% margin), and multithread performance (37,084 versus 35,912, a 3.3% lead). The single-thread test also favors the Ultra 7 265T, posting 4,338 versus 4,017, an 8% advantage. The overall average benchmark score puts the Ultra 7 265T at 47,697 versus 47,176 for the i9-12900F, placing both in the 90th and 89th percentiles of all CPUs, respectively.

A: The Ultra 7 265T has 20 cores and 20 threads, while the i9-12900F has 16 cores and 24 threads. The i9-12900F’s higher thread count comes from Hyper-Threading, while the Ultra 7 265T relies on more physical cores.

Q: Which processor has a higher boost clock?

A: The Ultra 7 265T boosts to 5.30 GHz, which is 200 MHz higher than the i9-12900F’s 5.10 GHz. The base clocks differ as well, with the Ultra 7 265T at 1.50 GHz and the i9-12900F at 2.40 GHz.

Q: Do both processors support the same memory types?

A: No. The Ultra 7 265T supports DDR5 only, while the i9-12900F supports both DDR4 and DDR5. Memory bandwidth also differs, with the Ultra 7 265T at 102.4 GB/s versus 76.8 GB/s for the i9-12900F.

Where Each One Wins

The Ultra 7 265T is the clear choice for floating-point-heavy and mathematical workloads. Its 34.6% lead in floating point math and 153.5% lead in prime number finding make it ideal for scientific computing, financial modeling, and any task that relies heavily on FPU throughput. The physics test result (29.8% faster) also suggests an edge in simulation and physics-based rendering. For everyday productivity and single-threaded responsiveness, the 8% single-thread advantage and consistent 3.8% Cinebench lead mean the Ultra 7 265T will feel snappier in most applications.

The i9-12900F dominates in integer-heavy and data-compression workloads. Its 19% lead in integer math and 18% lead in data compression point to strengths in database operations, file archiving, and code compilation. The 8.4% advantage in random string sorting further reinforces this profile, making it a better fit for server-style workloads, data processing pipelines, and tasks that manipulate large in-memory datasets. The 24 threads versus 20 also give it an edge in highly parallel integer workloads that can saturate all available threads.

For mixed usage, the Ultra 7 265T’s 3.3% lead in PassMark multithread and its wins in data encryption (17.6%) and extended instructions (1.2%) make it the more balanced performer. The i9-12900F’s wins are narrower in count but larger in magnitude, suggesting it excels specifically in integer-heavy server-like tasks rather than general-purpose computing.

Specification Differences

The most striking difference is TDP: the Ultra 7 265T draws 35W, while the i9-12900F is rated at 65W — a 30W gap that explains the former’s suitability for compact systems. Socket compatibility also diverges, with the Ultra 7 265T using Intel Socket 1851 and the i9-12900F using Intel Socket 1700. Core counts differ (20 versus 16), as do thread counts (20 versus 24). The Ultra 7 265T has a lower base clock (1.50 GHz versus 2.40 GHz) but a higher boost clock (5.30 GHz versus 5.10 GHz).

Memory support separates the two: the Ultra 7 265T supports only DDR5, while the i9-12900F supports both DDR4 and DDR5. Memory bandwidth is higher on the Ultra 7 265T at 102.4 GB/s versus 76.8 GB/s. ECC memory support exists on the i9-12900F but is absent on the Ultra 7 265T. PCIe lanes differ as well, with the Ultra 7 265T offering 20 Gen 5 lanes versus 16 Gen 5 lanes on the i9-12900F. The Ultra 7 265T includes integrated Arc Xe-LPG Graphics with 64 execution units, while the i9-12900F has no integrated graphics. The multiplier is unlocked on the i9-12900F but locked on the Ultra 7 265T. Launch MSRP for the Ultra 7 265T is $384, while the i9-12900F launched at $494.

Architecture Differences

The Ultra 7 265T is built on Arrow Lake-S architecture using a 3 nm process from TSMC, while the i9-12900F uses Alder Lake-S on Intel’s 10 nm process. This process advantage is reflected in the transistor count: the Ultra 7 265T packs 17,800 million transistors on a 243 mm² die, while the i9-12900F’s die size is 215 mm² with no listed transistor count. The cache hierarchies differ substantially: the Ultra 7 265T has 192 KB of L1 per core and 3 MB of L2 per core, while the i9-12900F has 80 KB of L1 per core and 1.25 MB of L2 per core. Both share 30 MB of L3 cache.

The Ultra 7 265T’s 20 cores are all physical, with no Hyper-Threading, while the i9-12900F uses a hybrid design with 16 cores and 24 threads. The foundry also differs, with TSMC producing the Ultra 7 265T and Intel fabricating the i9-12900F. The integrated graphics presence on the Ultra 7 265T (Arc Xe-LPG with 64EU) versus none on the i9-12900F is a notable feature divergence. The Ultra 7 265T was released on 2025-01-06, while the i9-12900F launched on 2022-01-03, reflecting a three-year gap in design philosophy. The Arrow Lake chip’s higher memory bandwidth and larger per-core caches align with its benchmark profile, which favors latency-sensitive and floating-point workloads.
