Intel Core 9 273PQE vs Intel Core i9-14900T Comparison

Intel Core 9 273PQE and Intel Core i9-14900T are both desktop processors on the Intel Socket 1700 platform, but they target very different operating points. The 273PQE is a 12-core Bartlett Lake part with a 5.90 GHz boost clock and a 125 W TDP, while the 14900T is a 24-core Raptor Lake Refresh part with a 5.50 GHz boost and a 35 W TDP. The benchmark data shows a clean sweep: the Core 9 273PQE wins all 17 recorded head-to-head tests, with advantages ranging from 7.4% to 63.7%. The i9-14900T does hold its own in a few specific workloads, but the overall performance gap is substantial.

Where Each One Wins

The recorded data shows no test where the Intel Core i9-14900T comes out ahead. Every single benchmark in the database, from Cinebench renders to PassMark math and encryption tests, is won by the Intel Core 9 273PQE. That said, the margin of victory varies widely by workload, which indicates where each chip is relatively stronger or weaker.

The 273PQE dominates in heavily parallelized and vectorized tasks. Its largest wins are in PassMark extended instructions (63.7% ahead), floating point math (35.4% ahead), and data compression (34.3% ahead). These are workloads that scale with raw execution resources and high clock speeds, and the 273PQE’s 5.90 GHz boost clock is a clear factor.

The 14900T, despite losing every test, is closest in tasks that are less dependent on peak frequency. The smallest gap is in PassMark random string sorting, where the 273PQE leads by only 7.4%. Data encryption is also relatively close at 9.5%. These single-threaded or memory-latency-sensitive tasks narrow the gap because the 14900T’s higher core count and shared 36 MB L3 cache help it keep pace, even at a much lower 1.10 GHz base clock.

For users running Cinebench R23 multi-core, the 273PQE scores 39190 against 30803 for the 14900T. That is a 27.2% lead and reflects the 273PQE’s ability to sustain high all-core clocks within a 125 W envelope. The 14900T is a 35 W part, so its 24 cores are heavily power-limited, which explains why the 12-core 273PQE pulls ahead by more than a quarter in sustained multi-threaded loads.

Architecture Differences

The two processors come from different Intel generations and microarchitectures. The Intel Core 9 273PQE is built on Bartlett Lake, listed as a 10 nm process, and belongs to the Core 9 generation. The Intel Core i9-14900T uses Raptor Lake architecture, specifically the Raptor Lake-R refresh, also on a 10 nm process at Intel’s foundry. Both are fabricated by Intel, so the process node is identical.

Core counts differ significantly. The 273PQE has 12 cores and 24 threads, while the 14900T has 24 cores and 32 threads. The 14900T’s extra cores are likely efficiency-oriented, given its 35 W TDP, but the database does not list a performance-core/efficiency-core split for either processor. The 14900T also has a larger die size at 257 mm², while the 273PQE’s die size is not recorded.

Cache configurations are identical on paper: each core gets 80 KB of L1 and 2 MB of L2, and both share 36 MB of L3. This means the 14900T’s additional cores do not come with additional shared cache, which may limit its scaling in cache-sensitive workloads. The 273PQE’s smaller core count, combined with the same 36 MB L3, gives each core more effective cache headroom.

Clock speeds are a major differentiator. The 273PQE runs a 3.40 GHz base clock and boosts to 5.90 GHz, while the 14900T runs a 1.10 GHz base and boosts to 5.50 GHz. The 273PQE’s base clock is over three times higher, which is a direct consequence of the TDP difference: 125 W versus 35 W. Both processors are multiplier-locked, so users cannot overclock either one.

Memory support is the same for both: DDR4 and DDR5, dual-channel. The 273PQE lists a memory bandwidth of 89.6 GB/s, while the 14900T’s bandwidth is not recorded. Both support ECC memory. PCIe connectivity is identical as well: Gen 5 with 16 CPU lanes. Integrated graphics are also the same, UHD Graphics 770, on both parts.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent 27.2% to 27.3% lead for the Core 9 273PQE across all six tests. In Cinebench R15 multi-core, the 273PQE scores 3950 against 3104, a 27.3% difference. Single-core R15 is 557 versus 438, also 27.2%. R20 multi-core is 16459 versus 12937, and R20 single-core is 2323 versus 1826. R23 multi-core is 39190 versus 30803, and R23 single-core is 5532 versus 4348. The uniformity of these deltas suggests the 273PQE’s clock advantage translates directly into both single-threaded and multi-threaded render performance, with no workload-specific quirks in the Cinebench engine.

PassMark results show a wider spread. The biggest win for the 273PQE is in extended instructions, where it scores 38743 against 23660, a 63.7% lead. This is the single largest delta in the entire dataset and indicates a major advantage in AVX-class or other extended instruction workloads. Floating point math follows at 35.4% (125546 versus 92699), and data compression at 34.3% (585752 versus 436066). These are all multi-threaded or SIMD-heavy tests where the 273PQE’s higher sustained clocks and efficient 12-core design outperform the 14900T’s power-limited 24-core layout.

Integer math shows a 19.2% lead (164629 versus 138149), and find prime numbers is 20.7% ahead (198 versus 164). PassMark multi-thread is 27.2% ahead (46107 versus 36239), matching the Cinebench multi-core delta exactly. Physics is 22.7% ahead (2754 versus 2245). Single-thread tests show a 13.9% lead (4573 versus 4016), which is smaller than the Cinebench single-core gap. Data encryption is 9.5% ahead (29636 versus 27062), and random string sorting is the closest result at 7.4% (53167 versus 49484).

The Verdict

The data points to the Intel Core 9 273PQE as the stronger performer in every recorded benchmark. It leads by 27.2% in Cinebench R23 multi-core, 27.2% in single-core, and by as much as 63.7% in PassMark extended instructions. Its higher boost clock of 5.90 GHz and 125 W TDP allow it to sustain performance that the 35 W 14900T cannot match, despite the 14900T’s 24-core count.

The Intel Core i9-14900T is the lower-power option, with a 35 W TDP and a 1.10 GHz base clock. It loses every head-to-head test, but the smallest gaps are in random string sorting (7.4%) and data encryption (9.5%). For workloads that are not heavily clock-bound, the 14900T’s 24 cores and 32 threads keep it competitive, but it never takes the lead.

Users who prioritize raw compute, especially in Cinebench renders, floating point math, and extended instruction workloads, should select the Core 9 273PQE. Its 125 W TDP and 5.90 GHz boost clock deliver consistent wins across the entire benchmark suite. Users who need a lower-power desktop processor with more cores and a 35 W envelope may consider the 14900T, but the recorded data shows a significant performance cost for that efficiency, with no benchmark win in favor of the 14900T.
