AMD Ryzen 7 1700X vs Intel Core i3-10105T Comparison

The Verdict

The benchmark data splits these two CPUs along clear lines. The AMD Ryzen 7 1700X is the decisive winner for multi-threaded workloads, taking three of the four head-to-head tests with commanding margins. The Intel Core i3-10105T claims only a single victory, in Geekbench single-core, but that win is narrow and does not offset the AMD part's dominance elsewhere.

The Ryzen 7 1700X delivers 129.4% higher Cinebench R15 multi-core performance than the i3-10105T, turning a 1537 score against 670. In Geekbench multi-core, the AMD chip leads by 53%, scoring 5584 versus 3649. Even in Cinebench R15 single-core, where the Intel part's higher 3.90 GHz boost should help, the Ryzen 7 1700X wins by 63.8%, posting 154 against 94. This is not a close contest; the 1700X is the pick for rendering, compilation, streaming, or any workload that scales across cores.

The i3-10105T does have one concrete advantage: Geekbench single-core, where it scores 1265 against 1100, a 13% lead for the Intel part. That makes it the better choice for lightly threaded applications that depend on single-thread responsiveness, such as older games or simple office tasks. However, the margin is modest, and the i3's overall average benchmark score of 2058 sits nearly level with the 1700X's 2094, a difference of roughly 1.7%. The percentile ranking against all CPUs is identical for both at 46, meaning they occupy the same overall performance tier despite their very different strengths.

For buyers who need raw multi-core throughput, the Ryzen 7 1700X is the clear choice. For buyers who prioritize single-thread speed and power efficiency, the i3-10105T deserves consideration, but its single win is the only benchmark where it leads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 1700X uses the Zen architecture on a 14 nm process from GlobalFoundries, with a die size of 213 mm² and 4,800 million transistors. It packs 8 cores and 16 threads, with a base clock of 3.40 GHz and a boost clock of 3.80 GHz. The Intel Core i3-10105T uses the Comet Lake architecture, also on a 14 nm process but from Intel, with no transistor or die size data recorded. It has 4 cores and 8 threads, a base clock of 3.00 GHz, and a higher boost clock of 3.90 GHz.

Cache layouts differ substantially. The Ryzen 7 1700X provides 96 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The i3-10105T offers 64 KB of L1 per core, 256 KB of L2 per core, and only 6 MB of shared L3. That larger L3 pool on the AMD side helps explain its multi-core advantage in cache-sensitive workloads.

The Ryzen 7 1700X supports ECC memory, while the i3-10105T does not. Both support DDR4 with dual-channel memory and identical 42.7 GB/s memory bandwidth, and both use PCIe Gen 3 with 16 lanes from the CPU. The Intel part includes integrated UHD Graphics 630, while the AMD part has no integrated graphics recorded. The Ryzen 7 1700X has an unlocked multiplier, the i3-10105T is locked.

Release dates differ by roughly four years: the 1700X launched on March 2017 at $399, while the i3-10105T launched March 2021 at $134. Both parts remain Active in production status.

The 1700X's 95 W TDP reflects its larger core count and older process, while the i3-10105T's 35 W TDP reflects its smaller footprint. Socket compatibility is entirely separate as well: AMD Socket AM4 versus Intel Socket 1200.

Specification Differences

The two CPUs differ in nearly every fundamental specification. The AMD Ryzen 7 1700X has 8 cores and 16 threads, while the Intel Core i3-10105T has 4 cores and 8 threads. Base clocks are 3.40 GHz for the AMD part and 3.00 GHz for the Intel part. The boost clock goes the other way: 3.80 GHz for the 1700X, 3.90 GHz for the i3-10105T.

TDP is a major differentiator. The 1700X draws 95 W, the i3-10105T draws only 35 W. The socket differs, with AM4 on the AMD side and Socket 1200 on the Intel side. Architecture names differ as well: Zen for the 1700X, Comet Lake for the i3-10105T. The process node is 14 nm for both, but the foundries differ: GlobalFoundries for AMD, Intel for the i3.

Cache configurations are not equal. The 1700X has 96 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. The i3-10105T has 64 KB L1 per core, 256 KB L2 per core, and 6 MB shared L3. The 1700X supports ECC memory, the i3-10105T does not. The i3-10105T includes UHD Graphics 630 integrated graphics, the 1700X has no integrated graphics recorded. The 1700X has an unlocked multiplier, the i3-10105T is locked. The 1700X launched March 2017 at $399 launch MSRP, the i3-10105T launched March 2021 at $134. The 1700X has a transistor count of 4,800 million and a die size of 213 mm², while the i3-10105T has no transistor count or die size recorded.

Head-to-Head Benchmarks

The recorded data shows three substantial wins for the AMD Ryzen 7 1700X and one for the Intel Core i3-10105T. In Cinebench R15 multi-core, the 1700X scores 1537 against 670 for the i3-10105T, a 129.4% advantage. In Geekbench multi-core, the 1700X posts 5584 against 3649, a 53% lead. Even in Cinebench R15 single-core, the 1700X wins 154 to 94, a 63.8% margin. The i3-10105T's only win comes in Geekbench single-core, where it scores 1265 against 1100, a 13% advantage.

These results track the core and thread counts directly. The 1700X has double the cores and double the threads, and its multi-core margins are enormous. The i3-10105T's higher boost clock of 3.90 GHz does not prevent the 1700X from winning Cinebench R15 single-core, which indicates the older Zen core still outruns the Comet Lake core in that specific workload. Only in Geekbench single-core does the Intel design show its strength, and even then the lead is modest relative to the AMD part's multi-core dominance.

The average benchmark scores tell a similar story from a different angle. The 1700X averages 2094, the i3-10105T averages 2058. The 1700X's nearest rival, the Intel Core i3-8350K, averages 2096 with a delta of -0.1%, while the i3-10105T's nearest rival, the Intel Core i7-8705G, averages 2058 with a delta of 0%. Both chips sit within 2% of each other on average, yet their benchmark profiles could hardly be more different.

Where Each One Wins

The AMD Ryzen 7 1700X wins in every multi-core scenario and in Cinebench R15 single-core. Its 129.4% lead in Cinebench R15 multi-core makes it the obvious choice for video rendering, 3D modeling, batch photo processing, software compilation, and any workload that can use 8 cores and 16 threads. The 53% Geekbench multi-core lead reinforces this conclusion. The 1700X also wins Cinebench R15 single-core by 63.8%, an unexpected result given the i3's boost clock advantage, which suggests the AMD part is faster even in at least one single-threaded test.

The Intel Core i3-10105T wins Geekbench single-core by 13%, which makes it the better pick for applications that are strictly single-threaded and sensitive to per-core performance, such as older games, or for general desktop responsiveness in workflows that rarely use more than one core at a glance. The 35 W TDP is the lowest recorded between the two parts, so for users who value power efficiency alongside single-thread speed, the i3-10105T is the more conservative energy-friendly option, though power consumption figures beyond TDP are not recorded in the data.

The i3-10105T also includes integrated UHD Graphics 630, which means users can run a display output without needing a separate GPU, while the 1700X requires a discrete graphics solution. For a low-power desktop build with minimal multi-core demands, the i3-10105T is the logical pick. For a high-throughput desktop CPU that excels in multi-threaded productivity, the 1700X is the winner without qualification. The wins split breaks down as 3 for the AMD part and 4 for the i3-10105T in terms of benchmark victories, with the i3's single win standing alone as its only claim to relevance in this comparison.
