Intel Core i9-13900TE vs Intel Core i9-7920X Comparison

Head-to-Head Benchmarks

The recorded head-to-head data is unusually one-sided. Across six Cinebench tests, the Intel Core i9-7920X wins every single comparison, with deltas clustering tightly between 8.2% and 8.4%. The largest margin comes in Cinebench R15 single-core, where the i9-7920X scores 284 against 262 for the i9-13900TE, a lead of 8.4%. The smallest gap, 8.2%, appears in Cinebench R20 multi-core, R23 multi-core, and R23 single-core, though the absolute scores differ substantially.

Looking at multi-threaded workloads first, the i9-7920X posts 2015 in Cinebench R15 multi-core versus 1861 for the i9-13900TE. That 154-point gap translates to an 8.3% advantage. In Cinebench R20 multi-core, the delta is again 8.2%, with scores of 8396 and 7758 respectively. The most demanding test, Cinebench R23 multi-core, shows the same pattern: 19991 for the i9-7920X against 18472 for the i9-13900TE. The consistency of these margins across different Cinebench versions suggests the performance relationship between the two chips is stable regardless of workload scaling.

Single-core results tell the same story. Cinebench R15 single-core gives the i9-7920X a 284 score, 8.4% above the i9-13900TE's 262. In Cinebench R20 single-core, the i9-7920X reaches 1185 versus 1094, an 8.3% edge. Cinebench R23 single-core closes the gap slightly to 8.2%, with 2822 against 2607. The i9-7920X wins all six head-to-head matchups, leaving the i9-13900TE with zero wins in this dataset.

The overall benchmark averages reflect this dominance, though not perfectly. The i9-7920X carries an average benchmark score of 5673 across all recorded tests, while the i9-13900TE averages 5342. That difference of 331 points is roughly 6.2%, slightly smaller than the Cinebench deltas because the i9-7920X also has Geekbench results in its record. In Geekbench multi-core, the i9-7920X scores 9297, and in Geekbench single-core it scores 1394. The i9-13900TE has no Geekbench entries in the database, so its average relies solely on the six Cinebench runs.

Percentile rankings place both processors close together in the broader CPU landscape. The i9-7920X sits at the 61st percentile against all CPUs, while the i9-13900TE lands at the 60th. The nearest rivals for the i9-7920X include the AMD EPYC 7F32, which scores 5703 on average with a delta of -0.5%, and the AMD EPYC 7351 at 5710 with -0.6%. The AMD Ryzen Threadripper 2920X trails by 1% at 5730, while the AMD Ryzen 7 PRO 3700 is 1.1% ahead at 5610. For the i9-13900TE, the Intel Core i9-10900KF averages 5316 with a 0.5% delta, the AMD EPYC 7281 averages 5315 with 0.5%, the AMD Ryzen Threadripper 1920X averages 5306 with 0.7%, and the Intel Core i9-9900X averages 5301 with 0.8%.

Architecture Differences

The most striking architectural contrast lies in core counts and process technology. The i9-7920X uses a Skylake-X design on Intel's 14 nm node, packing 12 cores and 24 threads. The i9-13900TE is built on Raptor Lake-S using a 10 nm process, with 24 cores and 32 threads. Despite having half the cores, the i9-7920X still outpaces the i9-13900TE in every measured Cinebench test, which indicates that raw core count alone does not determine the outcome. The i9-13900TE's extra 12 cores and 8 additional threads do not translate into a multi-core win, likely because of differences in clock behavior under the power envelope.

Clock speeds differ dramatically. The i9-7920X lists a base clock of 2.90 GHz and a boost clock of 4.40 GHz. The i9-13900TE lists a base clock of 1000.00 MHz, which the database records as its base operating point, and a boost clock of 5.00 GHz. The i9-13900TE can reach a higher peak frequency, yet it still loses single-core tests by roughly 8.2% to 8.4%. This suggests the sustained operating characteristics, not the theoretical maximum boost, drive the benchmark results.

Power consumption separates the two sharply. The i9-7920X has a TDP of 140 watts, while the i9-13900TE is rated at 35 watts. That fourfold difference in thermal design power explains much of the performance relationship. The i9-7920X can draw substantially more power to maintain higher sustained clocks across its 12 cores. The i9-13900TE, designed for a much lower power budget, cannot sustain comparable performance despite having more cores and a higher boost clock.

Cache hierarchies also differ. The i9-7920X provides 64 KB of L1 cache per core, 1 MB of L2 per core, and 16.5 MB of shared L3. The i9-13900TE provides 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The i9-13900TE has roughly twice the L3 capacity and larger per-core L1 and L2 allocations, yet the benchmark results do not favor it. Die size and process node reflect the generational shift: the i9-7920X measures 484 mm² on 14 nm, while the i9-13900TE measures 257 mm² on 10 nm. The newer process allows the i9-13900TE to fit more cores into a smaller die.

Memory support diverges as well. The i9-7920X uses DDR4 with a quad-channel memory bus and a recorded memory bandwidth of 85.3 GB/s. The i9-13900TE supports both DDR4 and DDR5, but uses a dual-channel memory bus, and no memory bandwidth figure is recorded in the database. The i9-7920X also has 44 PCIe Gen 3 lanes from the CPU, while the i9-13900TE offers 16 PCIe Gen 5 lanes. The i9-13900TE includes integrated graphics in the form of UHD Graphics 770, whereas the i9-7920X has no integrated graphics listed. ECC memory support is another differentiator: the i9-13900TE supports ECC, while the i9-7920X does not.

The Verdict

The data points to a clear winner in raw benchmark performance: the Intel Core i9-7920X. It wins all six head-to-head Cinebench comparisons and holds a higher average benchmark score (5673 versus 5342). It also ranks slightly higher in percentile terms, at 61 versus 60. Buyers who prioritize maximum measured performance in the workloads represented by Cinebench should select the i9-7920X based strictly on these results.

However, the i9-13900TE is not without merit. It offers 24 cores and 32 threads compared to 12 cores and 24 threads. It supports both DDR4 and DDR5 memory, includes ECC memory support, and has integrated graphics. Its TDP of 35 watts is dramatically lower than the i9-7920X's 140 watts, which matters for systems where thermal output and power draw are critical constraints. Its 10 nm process and smaller 257 mm² die also indicate a more modern manufacturing approach. For workloads that are not captured in the Cinebench suite, such as those that heavily leverage the i9-13900TE's extra cores or its integrated GPU, the i9-13900TE may be the more appropriate choice even though the recorded benchmarks do not favor it.

The i9-7920X is end-of-life, while the i9-13900TE remains active in production. The i9-7920X launched with a launch MSRP of $1199, while the i9-13900TE has no recorded launch MSRP. The i9-7920X has an unlocked multiplier, whereas the i9-13900TE does not. These factors may influence purchasing decisions beyond the benchmark scores. The verdict from the measured data is straightforward: the i9-7920X is the faster processor in every recorded Cinebench test, but the i9-13900TE offers a different balance of features, power efficiency, and modern platform support.

The i9-7920X further distinguishes itself with a quad-channel memory bus, 85.3 GB/s of recorded memory bandwidth, 44 PCIe Gen 3 lanes, and an unlocked multiplier for overclocking. Its launch MSRP of $1199 places it in the high-end desktop segment, though that figure is now historical given its end-of-life status.

The i9-13900TE wins in areas outside the measured benchmarks. It has double the core count (24 versus 12) and more threads (32 versus 24). It supports both DDR4 and DDR5 memory, while the i9-7920X is limited to DDR4. It includes ECC memory support, which the i9-7920X lacks. It has integrated graphics with UHD Graphics 770, allowing for display output without a discrete GPU. Its TDP of 35 watts is far lower than the i9-7920X's 140 watts, making it suitable for power-constrained environments. It uses a more modern 10 nm process and a smaller 257 mm² die. It offers PCIe Gen 5 connectivity with 16 lanes. It remains active in production, while the i9-7920X is end-of-life. Its base clock is recorded at 1000.00 MHz, but its boost clock reaches 5.00 GHz, higher than the i9-7920X's 4.40 GHz peak.

The use-case split is therefore clear. For pure compute performance as measured by Cinebench, the i9-7920X is the superior choice. For systems that need modern platform features, ECC memory, integrated graphics, lower power consumption, or dual-channel memory with DDR5 support, the i9-13900TE offers capabilities the i9-7920X cannot match. The i9-7920X suits workloads where sustained multi-threaded and single-threaded Cinebench performance is the primary concern.
