AMD Ryzen 9 7900X vs Intel Core i9-14900T Comparison

The Verdict

The data presents a clear split between these two desktop processors. The AMD Ryzen 9 7900X wins 12 of the 15 recorded head-to-head benchmarks, while the Intel Core i9-14900T takes 3. However, the nature of those wins matters more than the count. The AMD part dominates heavily in multi-threaded and specialized workloads, often by margins of 30% to over 100%. The Intel part wins decisively in single-core Cinebench tests, with its R23 single-core score of 4348 standing 53.6% above the AMD's 2016.5, and its R15 single-core score of 438 beating the AMD's 323 by 26.3%.

For users prioritizing raw multi-threaded throughput, particularly in data compression, encryption, extended instruction sets, or prime number finding, the Ryzen 9 7900X is the clear choice from the benchmark data. Its Passmark multithread score of 51406 is 41.9% higher than the Intel's 36239. For users whose primary applications rely on single-thread performance, especially in legacy Cinebench R15 or newer R23 single-core tests, the Core i9-14900T holds the advantage. The Intel part also carries a much lower 35 W TDP compared to the AMD's 170 W, which suggests it may be suited for thermally constrained systems, though the database does not record cooling or power consumption test results.

The overall average benchmark scores place the AMD at 53288 (91st percentile) and the Intel at 51015 (90th percentile), a difference of roughly 4.5%. The nearest rivals for each confirm their positioning: the AMD sits within 0.6% of the Intel Xeon 634 and 0.2% of the AMD EPYC 7313P, while the Intel trades within 1.1% of the AMD Ryzen AI 9 HX PRO 370 and 0.5% of the Intel Core i7-13850HX. Neither processor is far from its closest competitors, but the AMD part edges ahead in aggregate.

Where Each One Wins

The Ryzen 9 7900X wins across almost every Passmark workload category. It leads in data compression by 45%, data encryption by 37.7%, extended instructions by 101.3%, find prime numbers by 136.6%, floating point math by 12.1%, integer math by 22.5%, multithread by 41.9%, physics by 36.3%, and random string sorting by 50.9%. It also wins in single-thread Passmark by 5.5%, posting 4238 against the Intel's 4016. The Cinebench R15 multicore test goes to the AMD as well, with a 55.3% advantage (4820.5 versus 3104).

The Core i9-14900T wins the Cinebench R15 single-core test by 26.3%, the Cinebench R23 multicore test by 4.9% (30803 versus 29300), and the Cinebench R23 single-core test by 53.6%. These three wins are concentrated in Cinebench workloads, suggesting the Intel part has specific strength in rendering tasks that use the Cinebench engine, particularly in single-threaded modes.

The use-case split is therefore straightforward from the data. The AMD part is the multi-workload champion, excelling in mathematical, encryption, and data-processing tasks. The Intel part is the Cinebench specialist, with its single-core performance being particularly notable. For users running diverse productivity suites that include compression, encryption, or extended instruction workloads, the AMD part's margins are substantial. For users focused on Cinebench-based rendering or single-thread-dependent applications, the Intel part offers the higher scores.

Architecture Differences

The two processors come from different manufacturers and use fundamentally different designs. The AMD Ryzen 9 7900X is a 12-core, 24-thread part based on the Zen 4 architecture, codenamed Raphael, built on a 5 nm process at TSMC with 13,140 million transistors across a 2x 71 mm² die. The Intel Core i9-14900T is a 24-core, 32-thread part using the Raptor Lake architecture (Raptor Lake Refresh), built on a 10 nm process at Intel with a 257 mm² die size. The Intel part's core count includes both performance and efficiency cores, though the database does not specify the core type split.

Cache configurations differ markedly. The AMD part has 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. The Intel part has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The AMD's larger L3 pool may contribute to its strong performance in data-heavy workloads, while the Intel's larger per-core L1 and L2 could aid in latency-sensitive single-thread tasks.

Memory support diverges as well. The AMD part supports only DDR5 memory with a dual-channel bus and a recorded bandwidth of 83.2 GB/s. The Intel part supports both DDR4 and DDR5, also dual-channel, but the database does not record its memory bandwidth. Both support ECC memory. PCIe connectivity differs: the AMD offers Gen 5 with 24 lanes (CPU only), while the Intel offers Gen 5 with 16 lanes (CPU only). Integrated graphics differ, with the AMD featuring Radeon Graphics and the Intel featuring UHD Graphics 770.

The sockets are incompatible: AMD Socket AM5 for the Ryzen, Intel Socket 1700 for the Core i9. The AMD part has an unlocked multiplier, while the Intel part is locked. The AMD part released on 2022-09-26, the Intel part on 2024-01-07. Both carry a launch MSRP of $549 and are in active production. The base clocks differ substantially: the AMD runs at 4.70 GHz base with a 5.60 GHz boost, while the Intel runs at 1.10 GHz base with a 5.50 GHz boost. The AMD's TDP is 170 W, the Intel's is 35 W.

The next biggest is in extended instructions, where the AMD's 47619 is 101.3% higher than the Intel's 23660. Data compression shows a 45% advantage (632505 versus 436066), and random string sorting shows a 50.9% edge (74658 versus 49484). Data encryption is 37.7% higher (37263 versus 27062), and physics is 36.3% higher (3060 versus 2245). Integer math is 22.5% higher (169273 versus 138149), and floating point math is 12.1% higher (103952 versus 92699). In Passmark multithread, the AMD leads by 41.9% (51406 versus 36239). In Passmark single-thread, the AMD leads by 5.5% (4238 versus 4016). In Cinebench R15 multicore, the AMD leads by 55.3% (4820.5 versus 3104).

The Intel Core i9-14900T's largest win is in Cinebench R23 single-core, where it scores 4348 against the AMD's 2016.5, a 53.6% margin. Its Cinebench R15 single-core win is 26.3% (438 versus 323). Its Cinebench R23 multicore win is 4.9% (30803 versus 29300). Notably, the Intel's R23 multicore win is narrow compared to its single-core wins, and it loses the R15 multicore test by a wide margin.

These results show a consistent pattern. In Passmark-based workloads, the AMD part wins every test, often by large margins. In Cinebench, the Intel part wins three of four tests, with its single-core advantage being particularly pronounced. The single outlier is Cinebench R15 multicore, where the AMD wins decisively, suggesting the Intel's multicore advantage in R23 does not carry over to the older R15 test.
