AMD Ryzen 3 7320U vs Intel Core i3-10305T Comparison

Intel Core i3-10305T and AMD Ryzen 3 7320U land in the same performance tier, with average benchmark scores of 1922 and 1916 respectively — a gap of just 0.3% in favor of the Intel part. Both CPUs sit at the 43rd percentile of all processors tracked in the database. The head-to-head results, however, reveal a more complex picture: the AMD chip wins three of the four shared benchmarks, but the Intel chip wins the one test that matters most for sustained multi-threaded workloads. These are two very different designs — a 35 W desktop part built on Intel's 14 nm process versus a 15 W mobile part built on TSMC's 6 nm node — and their benchmark profiles reflect those divergent priorities.

Where Each One Wins

The AMD Ryzen 3 7320U dominates the single-core and lightly-threaded arena. In Cinebench R15 single-core, it scores 162.4 against the Intel chip's 94, a 42.1% advantage. The margin narrows in Cinebench R23 single-core, where the AMD leads 1095 to 938, a 14.3% difference. For everyday responsiveness, quick task switching, and applications that rely on one or two threads, the Ryzen 3 7320U is the clear pick. Its higher boost clock of 4.10 GHz, versus 4.00 GHz on the Intel, helps explain this edge, along with the architectural efficiency of Zen 2 on a modern 6 nm process.

The Intel Core i3-10305T wins the multi-core battle in the most demanding test. In Cinebench R23 multi-core, it scores 6647 against the AMD's 4809 — a 38.2% advantage. This is a substantial margin, and it suggests the Intel part is better suited for longer-running, fully-threaded workloads like video encoding, 3D rendering, or compiling. The Intel chip's larger 8 MB shared L3 cache, versus 4 MB on the AMD, likely contributes to this multi-core strength. Interestingly, the AMD wins Cinebench R15 multi-core 790 to 669, a 15.3% margin, but this older test may not fully stress sustained power delivery in the same way R23 does.

Head-to-Head Benchmarks

The shared benchmark suite between these two CPUs covers four tests: two Cinebench R15 variants and two Cinebench R23 variants. The AMD Ryzen 3 7320U wins three of these, but the one loss is decisive.

Starting with Cinebench R15 multi-core, the AMD chip scores 790 against the Intel's 669, a 15.3% victory. This is a solid win, but the older R15 test is shorter and less demanding on sustained power delivery. The single-core R15 test shows the AMD's biggest advantage: 162.4 versus 94, a 42.1% gap. This is a massive difference, nearly double the Intel score, and it highlights the architectural efficiency of Zen 2 at lower clocks.

Moving to Cinebench R23, the picture shifts. In single-core, the AMD still leads, scoring 1095 against 938, a 14.3% margin. This is a comfortable win, but notably smaller than the R15 single-core gap. The real reversal comes in R23 multi-core: the Intel Core i3-10305T scores 6647 against the AMD's 4809, a 38.2% advantage. This is the largest margin in either direction across all four tests. The Intel chip's 8 MB of shared L3 cache, double the AMD's 4 MB, likely plays a role here, as does its ability to sustain higher clocks under load despite its higher 35 W TDP.

The win count sits at 1 for Intel and 3 for AMD, but the magnitude of the Intel win in R23 multi-core suggests that for heavily threaded applications, the Intel part is the stronger choice. The AMD's wins are spread across both single-core tests and the older multi-core test, indicating its strength in lighter, more responsive workloads.

Specification Differences

The two CPUs differ across nearly every major specification category. The Intel Core i3-10305T is a desktop part with a 35 W TDP, while the AMD Ryzen 3 7320U is a mobile part with a 15 W TDP. This power difference is significant, but the Intel chip uses it to maintain a base clock of 3.00 GHz versus the AMD's 2.40 GHz. The boost clocks are closer: 4.00 GHz on Intel versus 4.10 GHz on AMD.

The cache configurations diverge notably. Both share the same 64 KB L1 per core, but the L2 cache differs: 256 KB per core on Intel versus 512 KB per core on AMD. The L3 cache is where Intel takes a clear lead, with 8 MB shared versus 4 MB shared on AMD. This larger L3 is a likely factor in the Intel's strong R23 multi-core performance.

Memory support is entirely different. The Intel chip uses DDR4 with dual-channel memory and a bandwidth of 42.7 GB/s. The AMD chip uses LPDDR5, also dual-channel, but with a much higher bandwidth of 88.0 GB/s. The AMD's memory bandwidth advantage is substantial, though it does not translate into a multi-core win in R23.

PCIe support also differs: the Intel part offers Gen 3 with 16 lanes (CPU only), while the AMD part offers Gen 3 with just 4 lanes (CPU only). This makes the Intel chip far more suitable for desktop expansion. The integrated graphics are different as well: Intel has UHD Graphics 630, while AMD has Radeon 610M. The Intel part carries a launch MSRP of $143; the AMD part has no listed launch MSRP.

Architecture Differences

The architectural divide is stark. The Intel Core i3-10305T is built on Comet Lake, specifically Comet Lake-R, using a 14 nm process from Intel. The AMD Ryzen 3 7320U is built on Zen 2, codenamed Mendocino, using a 6 nm process from TSMC. The process node difference is significant: 14 nm versus 6 nm, which explains the AMD's superior power efficiency at a 15 W TDP.

The Intel part has a die size that is not listed, while the AMD die is listed at 100 mm². Neither part has transistor counts listed. The generational naming reflects the gap: Intel's is "Core i3 (Comet Lake)" while AMD's is "Ryzen 3 (Zen 2 (Mendocino))". Both CPUs have 4 cores and 8 threads, so the thread count is identical. Neither has an unlocked multiplier.

The socket types are incompatible: Intel uses Socket 1200, while AMD uses Socket FT6. The market segments also differ, with Intel targeting desktop and AMD targeting mobile. The production status for both is listed as "Active." The Intel part number is SRH3M, while AMD's is 100-000000676.

The Verdict

The data points to a clear split based on use case. For a desktop system where sustained multi-threaded performance is the priority, the Intel Core i3-10305T is the stronger choice. Its 38.2% lead in Cinebench R23 multi-core is decisive, and its 8 MB L3 cache provides a meaningful advantage for heavily threaded applications. The Intel part also offers 16 PCIe Gen 3 lanes, making it far more flexible for desktop expansion cards. Its launch MSRP is $143, though pricing comparisons are beyond the scope of this analysis.

For a mobile or power-constrained system where single-threaded responsiveness and efficiency matter more, the AMD Ryzen 3 7320U is the better option. It wins all three of the other head-to-head benchmarks, including a 42.1% margin in Cinebench R15 single-core. Its 15 W TDP is less than half the Intel's 35 W, making it ideal for thin-and-light laptops. The AMD chip's 88.0 GB/s memory bandwidth, nearly double the Intel's 42.7 GB/s, also suggests it can handle memory-intensive tasks more fluidly.

The average benchmark scores are nearly identical — 1922 versus 1916 — and both sit at the 43rd percentile. This means neither CPU is a clear overall winner; they are simply optimized for different environments. The Intel part is a desktop workhorse with a multi-core edge, while the AMD part is a mobile efficiency champion with a single-core lead. Buyers should choose based on their platform and workload: desktop users with threaded tasks should favor Intel, while laptop users prioritizing responsiveness and battery life should favor AMD.
