AMD Ryzen 3 5125C vs Intel Core i3-10305T Comparison

Head-to-Head Benchmarks

The recorded data for these two processors comes from different benchmark suites, so direct score-to-score comparisons are limited. The Intel Core i3-10305T has results from the Cinebench series, while the AMD Ryzen 3 5125C only carries Geekbench scores. This makes a clean apples-to-apples comparison impossible, but the aggregate data still tells a clear story.

Looking at the average benchmark score, the Intel part sits at 1922, while the AMD chip records 1902. That is a 20-point gap, roughly 1% in Intel’s favor. Both processors land at the 43rd percentile among all CPUs in the database, meaning they occupy the same performance tier despite their architectural differences. The nearest rivals for the Intel chip include the Intel Xeon E3-1231 v3 at 1925 (0.2% ahead), the Intel Core i7-6700T at 1918 (0.2% behind), and the AMD Ryzen 3 7320U at 1916 (0.3% behind). The AMD Ryzen 3 5125C sits near the Intel Core i3-9100F at 1903 (0.1% behind), the Intel Xeon E5-2620 v3 at 1907 (0.3% behind), and the AMD Ryzen 5 PRO 2400GE at 1910 (0.4% behind). These deltas are tiny, all within a fraction of a percent, so the two chips are effectively peers in overall performance.

The Intel i3-10305T shows its strength in multi-threaded workloads. Its Cinebench R23 multicore score is 6647, and its R20 multicore result is 2791. The R15 multicore score comes in at 669. Single-core results are more modest: 938 in R23, 393 in R20, and 94 in R15. The AMD Ryzen 3 5125C, by contrast, posts a Geekbench multicore score of 2566 and a single-core score of 1237. Without a shared benchmark, the direct comparison relies on the average scores, which favor Intel by a hair. The data shows both chips trading blows within a narrow band, and neither holds a decisive edge in the aggregate.

Architecture Differences

The Intel Core i3-10305T is built on Intel’s Comet Lake architecture, specifically the Comet Lake-R refresh, using a 14 nm process node fabricated by Intel. It has 4 cores and 8 threads, with a base clock of 3.00 GHz and a boost clock of 4.00 GHz. The L1 cache is 64 KB per core, L2 is 256 KB per core, and L3 is 8 MB shared. It supports DDR4 memory through a dual-channel bus with a memory bandwidth of 42.7 GB/s. The integrated graphics are UHD Graphics 630. PCIe support is Gen 3 with 16 lanes from the CPU. This is a desktop part, released in March 2021, with a launch MSRP of $143.

The AMD Ryzen 3 5125C uses the Zen 3 architecture, codenamed Cezanne-U, built on a 7 nm process at TSMC. It has 2 cores and 4 threads, with a base clock of 3.00 GHz and no listed boost clock. L1 cache is 64 KB per core, L2 is 512 KB per core, and L3 is 8 MB shared. Memory support is DDR4 on a dual-channel bus, with a higher memory bandwidth of 51.2 GB/s. The integrated graphics are Radeon Vega 3. PCIe support is Gen 3 with only 8 lanes from the CPU. The transistor count is 10,700 million on a 180 mm² die, and the chip is a mobile part released in May 2022. The power envelope is dramatically different: the Intel chip has a TDP of 35 watts, while the AMD chip runs at 15 watts.

The process node advantage is significant. AMD’s 7 nm TSMC process is much denser than Intel’s 14 nm, which helps explain the lower TDP despite the similar cache layout. Both chips have the same L3 cache size, but the AMD part doubles the L2 cache per core. The PCIe lane count also differs, with Intel offering 16 lanes versus AMD’s 8, which matters for desktop expansion but is less relevant in a mobile context.

Where Each One Wins

The Intel Core i3-10305T wins in scenarios that demand more threads. With 4 cores and 8 threads versus AMD’s 2 cores and 4 threads, the Intel part has a clear structural advantage in multi-threaded work. Its Cinebench R23 multicore score of 6647 reflects that capacity. For a desktop user running parallel workloads, video encoding, or compilation tasks, the Intel chip’s extra cores and threads provide a tangible benefit. The data shows its multicore scores are solid for its class, and the 35-watt TDP indicates it can sustain those loads without throttling as aggressively as a low-power mobile part.

The AMD Ryzen 3 5125C wins in efficiency and single-thread performance relative to its power draw. Its Geekbench single-core score of 1237 is strong, and its 15-watt TDP means it sips power. For light-threaded tasks like web browsing, office work, or media playback, the AMD chip delivers competitive performance at a fraction of the power budget. The higher memory bandwidth of 51.2 GB/s also helps in memory-sensitive workloads, though the 2-core limit caps its multi-threaded potential. In a thin-and-light laptop, the Ryzen 3 5125C is the sensible choice; in a desktop tower with room for a bigger cooler, the Intel i3-10305T offers more raw throughput.

The average benchmark scores tell the same story: both are within 1% of each other overall, so neither dominates. The Intel part wins on thread count and desktop flexibility, while the AMD part wins on efficiency and process technology. The choice hinges on the use case, not on raw performance superiority.

Specification Differences

The two processors differ in several key specification fields. The Intel Core i3-10305T has 4 cores and 8 threads, while the AMD Ryzen 3 5125C has 2 cores and 4 threads. The Intel base clock is 3.00 GHz with a boost of 4.00 GHz; the AMD base clock is 3.00 GHz with no boost clock listed. TDP differs massively: 35 watts for Intel versus 15 watts for AMD. The socket is different as well: Intel Socket 1200 versus AMD Socket FP6. The process node is 14 nm for Intel versus 7 nm for AMD, with the AMD chip built at TSMC. Cache sizes differ in L2 only: 256 KB per core for Intel versus 512 KB per core for AMD; L1 and L3 are identical at 64 KB per core and 8 MB shared respectively. Memory bandwidth is 42.7 GB/s for Intel versus 51.2 GB/s for AMD. PCIe lanes are 16 for Intel versus 8 for AMD. Integrated graphics are UHD Graphics 630 versus Radeon Vega 3. Market segment is Desktop versus Mobile. Release dates differ: Intel in March 2021, AMD in May 2022. The Intel part has a launch MSRP of $143; the AMD part has no listed MSRP. Both use DDR4 memory, dual-channel buses, no ECC support, and neither has an unlocked multiplier.

The Verdict

The data points to a clear split based on workload and platform. The Intel Core i3-10305T is the pick for desktop users who need more multi-threaded muscle. Its 4 cores and 8 threads, combined with a 4.00 GHz boost clock, deliver Cinebench R23 multicore scores of 6647, which is strong for a 35-watt desktop chip. If you are building a compact desktop, doing light video work, or running any parallel tasks, the Intel part offers more headroom.

The AMD Ryzen 3 5125C is the pick for mobile users or anyone prioritizing efficiency. Its 15-watt TDP is less than half of Intel’s, yet its average benchmark score of 1902 sits within 1% of the Intel chip. The 7 nm process and higher memory bandwidth of 51.2 GB/s make it a superior choice for battery-powered systems. The Geekbench single-core score of 1237 shows it handles everyday tasks without complaint. For a laptop where thermals and battery life matter more than raw thread count, the AMD chip is the obvious choice.

Neither processor dominates. The average benchmark scores are nearly identical, and both sit at the 43rd percentile among all CPUs. The Intel part wins on threads and desktop connectivity with 16 PCIe lanes, while the AMD part wins on efficiency and process technology. Pick the Intel i3-10305T for a budget desktop build with room for a capable cooler; pick the AMD Ryzen 3 5125C for a thin laptop or a fanless system where every watt counts. The recorded data supports both choices, and the final decision should come down to the platform you are targeting.
