CPU Comparison

FAQ

Q: Which processor wins more benchmark comparisons?

A: The AMD Ryzen Threadripper 1920X wins 6 of the 8 head-to-head tests, while the Intel Core i5-13400T wins the remaining 2. The AMD chip takes every Cinebench R15, R20, and R23 test, while Intel wins both Geekbench tests.

Q: How large is the AMD chip’s lead in Cinebench tests?

A: In six Cinebench comparisons (R15, R20, and R23, both multi-core and single-core), the Threadripper 1920X leads by a consistent 15.3% deltaPct in every test except R20 single-core, where the margin is 15.4%. Scores range from 1979 vs 1716 in R15 multi-core up to 19640 vs 17029 in R23 multi-core.

Q: What are the Intel chip’s wins in Geekbench?

A: The Core i5-13400T beats the Threadripper 1920X by 29.8% in Geekbench multi-core (10227 vs 7178) and by 37.6% in Geekbench single-core (1899 vs 1185). These are substantial margins, especially in single-threaded performance.

Q: How do their average benchmark scores compare?

A: The Threadripper 1920X has an average benchmark score of 5306, while the Core i5-13400T sits at 5210. The difference is small, roughly 1.8%, and both processors land at the 60th percentile among all CPUs.

Q: Which chip has more cores and threads?

A: The AMD Ryzen Threadripper 1920X has 12 cores and 24 threads. The Intel Core i5-13400T has 10 cores and 16 threads. AMD’s chip also has a 32 MB L3 cache versus Intel’s 20 MB shared L3 cache.

Q: Do both processors support ECC memory?

A: No. Both the Threadripper 1920X and the Core i5-13400T list ECC memory as false in the data. Neither chip supports error-correcting memory.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen Threadripper 1920X uses the original Zen architecture (codename Whitehaven), built on a 14 nm process at GlobalFoundries. It packs 9,600 million transistors across a dual-die design with each die measuring 213 mm². The Intel Core i5-13400T uses Raptor Lake-S architecture, built on Intel’s 10 nm process with a single 215 mm² die.

Cache layouts diverge sharply. The Threadripper 1920X provides 96 KB of L1 cache per core, 512 KB of L2 per core, and 32 MB of L3 cache. The Core i5-13400T has 80 KB of L1 per core, a much larger 1.25 MB of L2 per core, but only 20 MB of shared L3. Intel’s larger per-core L2 helps offset its smaller L3 pool.

Memory architecture is another major split. The Threadripper 1920X supports quad-channel DDR4 with a rated memory bandwidth of 85.3 GB/s. The Core i5-13400T supports both DDR4 and DDR5 but runs dual-channel, with no memory bandwidth figure listed in the data. For PCIe, AMD offers Gen 3 with 60 CPU lanes, while Intel provides Gen 5 with 20 CPU lanes, a generational leap in per-lane bandwidth but far fewer lanes.

The Intel chip includes integrated graphics (UHD Graphics 730), while the AMD Threadripper has no integrated graphics at all. Both are desktop parts and both are currently marked as Active in production status. The Threadripper has an unlocked multiplier; the Core i5 does not. The Intel chip also uses the smaller Intel Socket 1700, while the AMD part uses the large AMD Socket SP3r2.

Head-to-Head Benchmarks

The headline story is remarkable: the AMD Ryzen Threadripper 1920X wins every single Cinebench test, and by almost exactly the same margin each time. In Cinebench R15 multi-core, AMD scores 1979 against Intel’s 1716, a 15.3% lead. In R15 single-core, the same 15.3% delta appears (279 vs 242). R20 multi-core shows 8248 vs 7152, again 15.3%. R20 single-core is 1164 vs 1009, a 15.4% edge. R23 multi-core is 19640 vs 17029, and R23 single-core is 2772 vs 2404, both 15.3% wins for AMD.

That consistency is striking. Across all three Cinebench versions, the Threadripper 1920X maintains nearly identical relative superiority, suggesting a uniform architectural advantage in that workload family. The Intel chip cannot close the gap in any Cinebench variant.

The Geekbench results flip the script entirely. The Core i5-13400T posts 10227 in Geekbench multi-core against AMD’s 7178, a 29.8% win. In single-core, Intel scores 1899 vs 1185, a massive 37.6% margin. These are not minor differences, the Intel chip is nearly 40% faster in Geekbench single-core, which indicates a substantial per-thread performance advantage that Cinebench does not capture.

The pattern suggests workload-dependent behavior. Cinebench favors the Threadripper’s higher core count and larger L3 cache, while Geekbench rewards the Core i5’s newer architecture and higher boost clock (4.40 GHz vs 4.00 GHz). The Intel chip’s base clock is listed as 1300.00 MHz, but its boost reaches 4.40 GHz, while AMD’s base is 3.50 GHz with a 4.00 GHz boost.

Specification Differences

The two chips differ in nearly every measurable category. Core count favors AMD: 12 cores and 24 threads vs Intel’s 10 cores and 16 threads. Clock speeds tell a split story, AMD has a higher base clock at 3.50 GHz vs Intel’s 1300.00 MHz, but Intel boosts higher at 4.40 GHz vs 4.00 GHz.

Thermal design power could not be more different. The Threadripper 1920X is rated at 180 W TDP, while the Core i5-13400T is rated at just 35 W. That is a massive power envelope difference, though the data does not include any performance-per-watt calculations.

Memory support diverges: AMD uses quad-channel DDR4 with 85.3 GB/s bandwidth; Intel uses dual-channel DDR4 or DDR5 with no bandwidth figure. PCIe generations differ (Gen 3 with 60 lanes for AMD vs Gen 5 with 20 lanes for Intel). Integrated graphics are absent on AMD, present on Intel as UHD Graphics 730.

Physical specifications also differ. AMD’s die size is two separate 213 mm² dies (total not stated), while Intel uses a single 215 mm² die. The transistor count is only listed for AMD at 9,600 million. Release dates are roughly five and a half years apart, August 2017 for AMD, January 2023 for Intel. The AMD part has an unlocked multiplier; Intel’s is locked. Launch MSRP is $799 for the Threadripper 1920X and $221 for the Core i5-13400T.

The Verdict

The data presents a clear but nuanced picture. The AMD Ryzen Threadripper 1920X dominates in Cinebench across every version, winning all six tests by a consistent 15.3% margin. Its 12-core, 24-thread configuration and 32 MB L3 cache give it a decisive edge in rendering workloads that scale with core count. If your work is Cinebench-style rendering, the Threadripper is the winner, plain and simple.

The Intel Core i5-13400T wins Geekbench convincingly, 29.8% in multi-core and 37.6% in single-core. Its Raptor Lake architecture, higher boost clock, and larger per-core L2 cache deliver modern per-thread performance that the older Zen design cannot match. The 35 W TDP also signals far lower power draw, though no efficiency metric is directly provided.

Average benchmark scores are nearly identical: 5306 for AMD vs 5210 for Intel, with both at the 60th percentile. The nearest rivals for each chip show similar company, AMD sits within 0.7% of the Intel Core i9-9900X, AMD EPYC 7281, Intel Core i9-10900KF, and Intel Core i9-13900TE. Intel’s rivals include the Intel Xeon E-2378G, Core i9-10850K, Core i7-11700B, and Core i5-14401E, all within 0.8%.

The launch MSRP difference is noted: $799 for AMD, $221 for Intel. Neither chip supports ECC memory. Both are active production parts. The choice depends entirely on which benchmark family reflects your actual workload.

Where Each One Wins

AMD Ryzen Threadripper 1920X, choose for Cinebench-style rendering: Every Cinebench test goes to AMD by 15.3%, from R15 through R23, both single-core and multi-core. The 12-core / 24-thread design, 32 MB L3 cache, and quad-channel DDR4 with 85.3 GB/s bandwidth make this the pick for heavily threaded render workloads. The unlocked multiplier and 60 PCIe Gen 3 lanes also suit workstation builds that need expansion. The 180 W TDP indicates serious power draw, but the rendering performance is consistently ahead.

Intel Core i5-13400T, choose for Geekbench-style general and single-threaded tasks: Intel wins Geekbench multi-core by 29.8% and single-core by 37.6%. The 4.40 GHz boost clock, larger per-core L2 cache (1.25 MB vs 512 KB), and newer Raptor Lake architecture drive this advantage. The 35 W TDP is a fraction of AMD’s power envelope, making it far easier to cool and integrate into compact systems. Integrated UHD Graphics 730 means it can run without a discrete GPU. The dual-channel DDR4/DDR5 support and 20 PCIe Gen 5 lanes offer modern connectivity at lower lane count.

The practical split: If your benchmark scores come from Cinebench, buy the Threadripper 1920X, it wins every test in that suite. If your scores come from Geekbench, buy the Core i5-13400T, it wins by margins two to three times larger than AMD’s Cinebench leads. The average scores are too close to separate them, so the decisive factor is which benchmark suite matches your daily workload.
