Intel Core i9-10900TE vs Intel Core i9-9900T Comparison

The Intel Core i9-10900TE is the outright winner in this comparison, taking all six head-to-head benchmarks against the Intel Core i9-9900T. The data shows a consistent performance advantage for the newer Comet Lake part, with the 10900TE leading by roughly 8% across both single-core and multi-core workloads. While the 9900T holds a higher percentile ranking among all CPUs (55th vs. 54th), the 10900TE’s superior core count and clock speeds make it the stronger processor for compute-heavy tasks.

Where Each One Wins

The benchmark split is entirely one-sided. The Intel Core i9-10900TE wins every single test in the head-to-head comparison, from Cinebench R15 to R23, in both single-core and multi-core modes. This means the 10900TE is the better choice for any workload that benefits from raw processing power, including video rendering, 3D modeling, and software compilation. The 9900T, by contrast, does not win a single benchmark in this matchup. Its only advantage is contextual: it sits at the 55th percentile of all CPUs, one point higher than the 10900TE’s 54th percentile, and its average benchmark score of 3499 is marginally higher than the 10900TE’s 3484. However, those aggregate statistics mask the fact that the 10900TE wins every direct comparison by a meaningful margin. For users prioritizing single-threaded responsiveness, the 10900TE still leads, with an 8.2% advantage in Cinebench R15 single-core and a 7.9% lead in R23 single-core.

Architecture Differences

The two processors come from different architectural generations. The Intel Core i9-9900T is built on Coffee Lake, specifically the Coffee Lake-R refresh, while the Intel Core i9-10900TE uses the Comet Lake architecture. Both are fabricated on Intel’s 14 nm process, but the die sizes differ: the 9900T measures 180.3 mm², while the 10900TE is larger at 206 mm². This size increase correlates with the 10900TE’s additional cores—it has 10 cores and 20 threads, compared to the 9900T’s 8 cores and 16 threads. The cache hierarchy also differs. Both feature 64 KB of L1 and 256 KB of L2 per core, but the shared L3 cache grows from 16 MB on the 9900T to 20 MB on the 10900TE. The sockets are incompatible: the 9900T uses Intel Socket 1151, while the 10900TE requires Intel Socket 1200. Both support DDR4 memory in dual-channel mode, but the 10900TE has a higher theoretical memory bandwidth at 46.9 GB/s versus 42.7 GB/s for the 9900T. Neither processor supports ECC memory, and both integrate UHD Graphics 630. The 10900TE also carries a higher base clock frequency—the data lists it as 1800.00 MHz, which is notably higher than the 9900T’s 2.10 GHz base clock, though the boost clocks are closer at 4.50 GHz versus 4.40 GHz.

Head-to-Head Benchmarks

The Cinebench results tell a consistent story. In Cinebench R15 multi-core, the 10900TE scores 1213 against the 9900T’s 1117, a 7.9% advantage. The single-core R15 test shows the 10900TE at 171 versus 157, an 8.2% lead. Moving to Cinebench R20, the 10900TE posts 5058 in multi-core, beating the 9900T’s 4658 by 7.9%. In single-core R20, the 10900TE scores 714, while the 9900T manages 657—an 8% difference. The newest Cinebench R23 test continues the pattern: the 10900TE scores 12045 in multi-core versus 11091 for the 9900T, and 1700 in single-core versus 1565, both with a 7.9% delta. The consistency of these deltas—hovering around 8%—suggests the 10900TE’s advantage comes from a combination of higher clock speeds and additional cores, rather than any single architectural improvement. The largest single-core gap is in R15 at 8.2%, while the multi-core gaps are uniform at 7.9% across all three Cinebench versions. Notably, the 9900T does have a Geekbench result—7298 multi-core and 1452 single-core—but the 10900TE has no Geekbench data in the fact pack, so no comparison is possible for that suite.

Specification Differences

The two CPUs differ in several key specifications. The core count is the most significant: the 9900T has 8 cores and 16 threads, while the 10900TE has 10 cores and 20 threads. The base clocks are listed as 2.10 GHz for the 9900T and 1800.00 MHz for the 10900TE, though the boost clocks are closer at 4.40 GHz and 4.50 GHz, respectively. The L3 cache grows from 16 MB on the 9900T to 20 MB on the 10900TE. The socket changes from Intel Socket 1151 to Intel Socket 1200. The die size is larger on the 10900TE at 206 mm² versus 180.3 mm². Memory bandwidth improves from 42.7 GB/s to 46.9 GB/s. The release dates differ by roughly a year, with the 9900T launching in April 2019 and the 10900TE in April 2020. The launch MSRP for the 9900T is $423, and for the 10900TE it is $488. Production status also differs: the 9900T is end-of-life, while the 10900TE is active. Both support PCIe Gen 3 with 16 lanes, both lack an unlocked multiplier, and both integrate UHD Graphics 630.

FAQ

Q: Which processor is faster in multi-core workloads?

A: The Intel Core i9-10900TE wins all three multi-core Cinebench tests. It scores 1213 in R15, 5058 in R20, and 12045 in R23, compared to the 9900T’s 1117, 4658, and 11091, respectively. The 10900TE leads by 7.9% in each case.

Q: Is the single-core performance gap similar to the multi-core gap?

A: Yes, the single-core deltas are nearly identical to the multi-core deltas. The 10900TE leads by 8.2% in Cinebench R15 single-core, and by 7.9% to 8% in R20 and R23 single-core tests.

Q: Do these processors use the same socket?

A: No. The 9900T uses Intel Socket 1151, while the 10900TE uses Intel Socket 1200. They are not interchangeable.

Q: Which CPU has more cache?

A: The 10900TE has more shared L3 cache at 20 MB, compared to 16 MB on the 9900T. Both have 64 KB of L1 and 256 KB of L2 per core.

Q: Are both processors still in production?

A: No. The 9900T is end-of-life, while the 10900TE is listed as active production.

Q: Which CPU has a higher boost clock?

A: The 10900TE boosts to 4.50 GHz, which is 100 MHz higher than the 9900T’s 4.40 GHz boost clock.

The Verdict

The benchmark data is unambiguous: the Intel Core i9-10900TE is the superior processor for anyone prioritizing raw performance. It wins all six head-to-head tests, with a consistent 8% advantage across both single-core and multi-core workloads. The 10900TE’s additional 2 cores and 4 threads, combined with a 100 MHz higher boost clock and 4 MB more L3 cache, translate directly into measurable performance gains. The 10900TE also offers higher memory bandwidth at 46.9 GB/s and a larger die, reflecting its more capable design. However, the 9900T is not without merit. It holds a slightly higher percentile ranking (55th vs. 54th) and a marginally higher average benchmark score (3499 vs. 3484), driven by its Geekbench results. For users on a Socket 1151 platform who cannot upgrade the motherboard, the 9900T remains a capable 8-core part, but it loses every direct comparison. The 10900TE’s active production status and newer release date also suggest better long-term availability. The data supports choosing the 10900TE for new builds or upgrades where the Socket 1200 platform is an option. The 9900T is only relevant for those already invested in its platform or seeking a lower launch MSRP of $423 versus $488.
