AMD Ryzen 9 5950X vs Intel Core i9-14900T Comparison

The Verdict

The AMD Ryzen 9 5950X and Intel Core i9-14900T are two very different answers to the same question, and the data makes the choice straightforward depending on what you prioritize. The Ryzen 9 5950X wins 9 of the 15 head-to-head benchmark comparisons, while the i9-14900T takes 6, but the type of wins matters more than the count. The 5950X dominates heavily in almost every multi-threaded PassMark workload — data compression, encryption, extended instructions, prime numbers, integer math, and multithread overall — with deltas ranging from 8.2% to 71%. The i9-14900T, by contrast, wins decisively in single-core tests and in the newer Cinebench R23 multi-core test, but its single-core advantage is enormous (62.9% in R23 single-core) while its multi-core wins are narrower or mixed.

If your workload is classic desktop computing — compression, encryption, math, sorting, and general parallel throughput — the 5950X is the clear pick from the benchmark data. If you need the best possible single-thread performance, or you run Cinebench R23-style rendering where the i9-14900T leads by 15.5%, the Intel chip is the better choice. The i9-14900T also has the advantage of a much lower 35W TDP versus 105W, making it the obvious choice for power-constrained builds. The 5950X sits at the 91st percentile among all CPUs, the i9-14900T at the 90th — statistically they are peers, with average benchmark scores of 51947 and 51015 respectively, a gap of only 1.8%.

Architecture Differences

The two chips could hardly be more different under the hood. The Ryzen 9 5950X is built on AMD's Zen 3 architecture, codenamed Vermeer, using a 7nm process from TSMC. It packs 16 cores and 32 threads, with a base clock of 3.40 GHz and a boost clock of 4.90 GHz. The die is composed of two 74 mm² chiplets, totaling 8,300 million transistors. The Intel Core i9-14900T uses Raptor Lake-R architecture, a refresh of Raptor Lake, on Intel's 10nm process with a single 257 mm² die. It offers 24 cores and 32 threads — meaning it relies on a mix of performance and efficiency cores to reach that thread count — with a base clock of just 1.10 GHz but a boost clock of 5.50 GHz.

Cache hierarchies also diverge significantly. The 5950X has 64 KB of L1 per core, 512 KB of L2 per core, and a large 64 MB of shared L3 cache. The i9-14900T has a larger 80 KB L1 per core and a much larger 2 MB L2 per core, but only 36 MB of shared L3. This means the Intel chip has more per-core cache for fast access, while the AMD chip has nearly double the total L3 for shared data. The i9-14900T also includes integrated graphics (UHD Graphics 770), while the 5950X has none. The AMD chip supports only DDR4 memory, dual-channel, with 51.2 GB/s bandwidth; the Intel chip supports both DDR4 and DDR5, also dual-channel, though its bandwidth figure is not listed. Both support ECC memory. PCIe generations differ: the 5950X offers Gen 4 with 20 lanes, while the i9-14900T offers Gen 5 with 16 lanes.

Head-to-Head Benchmarks

The biggest win for the AMD Ryzen 9 5950X comes in PassMark extended instructions, where it scores 40468 against the i9-14900T's 23660 — a 71% advantage. That is not a small margin; it indicates the 5950X handles advanced instruction sets far more efficiently. Data encryption is next, with the 5950X ahead by 46.3% (39593 vs 27062). Data compression follows at 43.2% (624347 vs 436066). Integer math shows a 34.3% lead (185520 vs 138149), and random string sorting is 31.7% better (65172 vs 49484). PassMark multithread overall favors the 5950X by 25.3% (45424 vs 36239), and find prime numbers shows a 39% advantage (228 vs 164). Floating-point math is a closer contest, with the 5950X winning by only 8.2% (100280 vs 92699).

The Intel Core i9-14900T's wins are concentrated in single-thread and Cinebench tests, and they are often dramatic. Cinebench R23 single-core is the standout: the i9-14900T scores 4348 versus 1614 for the 5950X, a 62.9% lead. Cinebench R15 single-core shows a similar pattern with a 39.2% advantage (438 vs 266.5). In Cinebench R23 multi-core, the i9-14900T wins with 30803 against 26017, a 15.5% margin. PassMark single-thread also goes to Intel by 13.6% (4016 vs 3470). The i9-14900T also wins PassMark physics by 16.3% (2245 vs 1878). Notably, in Cinebench R15 multi-core, the AMD chip wins decisively by 39.3% (4324 vs 3104), which contrasts sharply with the R23 multi-core result — suggesting the two chips scale very differently across Cinebench versions.

FAQ

Q: Which CPU has more cores and threads?

A: The Intel Core i9-14900T has more physical cores (24 vs 16), but both chips have the same thread count of 32. The Intel chip relies on a hybrid design to reach 24 cores with 32 threads, while the AMD chip uses 16 full cores with simultaneous multithreading.

Q: Does the Intel chip really have a lower TDP?

A: Yes, the i9-14900T has a TDP of 35W compared to the 5950X's 105W. That is a substantial difference — the Intel chip is rated for less than a third of the thermal envelope of the AMD chip, which makes it far easier to cool in compact or low-noise builds.

Q: Which chip wins in Cinebench R23 multi-core?

A: The Intel Core i9-14900T wins in Cinebench R23 multi-core, scoring 30803 against the 5950X's 26017, a 15.5% advantage. However, in the older Cinebench R15 multi-core test, the AMD chip wins by 39.3% (4324 vs 3104), so the result depends heavily on which version of Cinebench you use.

Q: Which chip has better single-thread performance?

A: The Intel Core i9-14900T is significantly better in single-thread tests. In Cinebench R23 single-core it scores 4348 versus 1614 for the AMD chip, a 62.9% lead. PassMark single-thread also favors Intel, with 4016 versus 3470, a 13.6% margin.

Q: Does the Intel chip have integrated graphics?

A: Yes, the i9-14900T includes UHD Graphics 770, while the AMD Ryzen 9 5950X has no integrated graphics at all. This means the Intel chip can run without a discrete GPU, while the AMD chip requires a separate graphics card for display output.

Q: Which chip supports DDR5 memory?

A: The Intel Core i9-14900T supports both DDR4 and DDR5 memory, while the AMD Ryzen 9 5950X supports only DDR4. The Intel chip is therefore the more future-proof option for memory upgrades, though its memory bandwidth figure is not listed in the data.

Where Each One Wins

The AMD Ryzen 9 5950X is the clear winner for compute-heavy parallel workloads that rely on raw throughput. Its PassMark results show dominance in data compression (43.2% ahead), data encryption (46.3% ahead), extended instructions (71% ahead), integer math (34.3% ahead), and random string sorting (31.7% ahead). If your daily driver involves file archiving, encryption, scientific computing, or any task that scales across many threads, the 5950X delivers substantially more work per unit of time. It also wins PassMark multithread overall by 25.3% and floating-point math by 8.2%, making it the better all-around number cruncher. The 5950X also wins Cinebench R15 multi-core by a massive 39.3%, indicating strong performance in older render workloads.

The Intel Core i9-14900T wins where single-thread speed and power efficiency matter most. Its single-core performance is unmatched in this comparison — 62.9% ahead in Cinebench R23 single-core and 39.2% ahead in R15 single-core — which translates to snappier everyday responsiveness and better performance in lightly threaded applications. It also wins Cinebench R23 multi-core by 15.5%, suggesting it is the better choice for current-generation rendering workloads. The i9-14900T wins PassMark physics by 16.3%, which is relevant for simulation and physics-based tasks. Most importantly, its 35W TDP versus the 5950X's 105W makes it the obvious choice for small form factor builds, low-noise systems, or any scenario where heat and power draw are primary constraints. The i9-14900T also has the advantage of integrated graphics, DDR5 support, PCIe Gen 5, and a lower launch MSRP of $549 versus $799, though pricing is noted only for reference. In short: pick the 5950X for maximum parallel compute per watt of silicon, and pick the i9-14900T for single-thread speed, modern platform features, and energy efficiency.
