AMD Ryzen 3 8300G vs Intel Core i3-13100 Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a clear split between these two quad-core processors. The AMD Ryzen 3 8300G wins 12 of the 17 head-to-head comparisons, while the Intel Core i3-13100 takes 5. The margins tell a more nuanced story than the raw win count, however. AMD's victories are often narrow in CPU-heavy workloads but substantial in specialized tests, while Intel's wins include one very large margin in floating-point math.

Starting with the render workloads, the Ryzen 3 8300G edges ahead consistently. In Cinebench R15 multi-core, AMD scores 1231 against Intel's 1208, a 1.9% lead. The single-core R15 result is 173 versus 170, also a 1.7% advantage for AMD. Moving to Cinebench R20, the pattern holds: 5131 against 5034 in multi-core and 724 against 710 in single-core, both 1.9% gaps. Cinebench R23 repeats the same 1.9% delta in both tests, with AMD posting 12217 multi-core and 1724 single-core, while Intel records 11986 and 1692 respectively. These are small but consistent margins across the entire Cinebench suite.

The PassMark suite reveals where each processor has clear strengths. AMD dominates in random string sorting with a 16.2% advantage, scoring 19013 against Intel's 15925. Data encryption is another decisive AMD win: 9115 versus 8049, an 11.7% gap. Extended instructions also favor AMD by 10.5%, with scores of 12354 and 11053. The single-threaded PassMark test shows AMD ahead by 8.4%, scoring 3778 against 3460. PassMark multithread gives AMD a narrower 2.1% win, 14018 versus 13726.

Intel's victories are more concentrated but include the largest single margin in the entire comparison. Floating-point math is a dominant win for Intel: 32325 against AMD's 25336, a 27.6% lead. Physics testing also favors Intel substantially, 870 versus 755, a 15.2% gap. Prime number finding gives Intel a 10.6% edge, 52 against 47.

Where Each One Wins

The AMD Ryzen 3 8300G is the pick for users who prioritize single-threaded responsiveness and data manipulation tasks. Its 8.4% lead in PassMark single-thread and consistent 1.7% to 1.9% margins across every Cinebench test indicate a processor that handles both light and heavy threaded workloads with slightly better efficiency. The 16.2% advantage in random string sorting suggests strong performance in database-style operations and text processing. Data encryption at 11.7% ahead makes it the better choice for security-focused workloads, while the 10.5% edge in extended instructions points to better support for specialized instruction sets.

The Intel Core i3-13100 wins where raw mathematical throughput matters most. The 27.6% lead in floating-point math is decisive for scientific computing, financial modeling, and any workload relying heavily on fractional calculations. Physics simulation shows a 15.2% advantage, making Intel the stronger option for physics-based rendering or engineering simulations. Prime number finding at 10.6% ahead suggests better performance in cryptography-related integer operations, though AMD counters with superior encryption throughput. Integer math is nearly even at 1.9% in Intel's favor, and data compression shows Intel ahead by 1.6%, a modest edge for archiving and file compression tasks.

For general desktop productivity, the AMD processor's multithread win of 2.1% and single-thread win of 8.4% make it the more balanced choice. The Intel processor's concentrated wins in floating-point and physics make it specialized rather than general-purpose. Users running mixed workloads will likely find AMD's broader consistency more valuable than Intel's narrow but deep advantages.

Specification Differences

Both processors share the same core and thread counts: 4 cores and 8 threads. Base clocks are identical at 3.40 GHz. Neither has an unlocked multiplier. Both use dual-channel memory buses. Both are active production parts for the desktop segment.

The differences begin with boost clock. The AMD Ryzen 3 8300G boosts to 4.90 GHz, while the Intel Core i3-13100 reaches 4.50 GHz. Thermal design power differs slightly: Intel is rated at 60 W, AMD at 65 W. Sockets are incompatible: Intel uses Socket 1700, AMD uses AM5. Memory support diverges significantly: Intel supports both DDR4 and DDR5, AMD supports only DDR5. AMD records a memory bandwidth figure of 83.2 GB/s, while Intel lists no bandwidth number. ECC memory is supported on AMD but not on Intel. PCIe generations differ: Intel offers Gen 5 with 16 lanes, AMD offers Gen 4 with 14 lanes. Integrated graphics are also different: Intel has UHD Graphics 730, AMD has Radeon 740M.

Release dates are about one year apart. Intel launched on 2023-01-03, AMD on 2024-01-07. Launch MSRP for Intel is $134, for AMD is $176. Intel's part number is SRMBU, AMD's is 100-000001492.

Architecture Differences

The architectural gap between these two is substantial. Intel builds the Core i3-13100 on Raptor Lake-S, using a 10 nm process at Intel's own foundry. The die size measures 163 mm². AMD uses Zen 4 architecture with the Phoenix2 codename, fabricated on a 4 nm process at TSMC. AMD's die is smaller at 137 mm², and the transistor count is listed at 20,900 million, while Intel does not report a transistor figure.

Cache hierarchies differ in both size and distribution. Intel allocates 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. AMD uses 64 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. The total cache footprint favors Intel, particularly in L3 where Intel's 12 MB is 50% larger than AMD's 8 MB. Neither processor supports 3D V-Cache.

The integrated graphics differ in brand and capability. Intel pairs its CPU with UHD Graphics 730, while AMD includes Radeon 740M. AMD's ECC memory support is a notable feature for workstation reliability. The PCIe generation difference (Gen 5 on Intel, Gen 4 on AMD) affects expandability for future peripherals, though AMD's 14 lanes versus Intel's 16 means fewer total lanes.

The manufacturing differences are stark: Intel's 10 nm process is two generations behind AMD's 4 nm node. Transistor density is not directly comparable without die size and count data, but the smaller die with more than 20 billion transistors on AMD suggests significantly higher density. Intel's larger die at 163 mm² with no transistor count leaves the comparison incomplete.

The Verdict

The benchmark data supports a clear conclusion: choose the AMD Ryzen 3 8300G for general computing, single-threaded tasks, and data processing. It wins 12 of 17 comparisons, including every Cinebench test and the PassMark multithread and single-thread tests. The 8.4% single-thread advantage and 16.2% random string sorting lead make it the better everyday processor. Its 4.90 GHz boost clock and 4 nm process node give it a modern foundation, and ECC memory support adds workstation appeal.

Choose the Intel Core i3-13100 for math-intensive workloads where floating-point performance is critical. The 27.6% lead in floating-point math is the largest margin in the entire comparison, and the 15.2% physics advantage reinforces Intel's strength in scientific and simulation tasks. The larger 12 MB L3 cache and 10 nm process (despite being older) still deliver strong results in integer math and compression. Intel's support for both DDR4 and DDR5 memory broadens platform compatibility, and the lower 60 W TDP offers modest power efficiency.

The average benchmark scores are nearly identical: 18380 for Intel versus 18169 for AMD. Both sit at the 72nd percentile. The real differentiator is workload type. AMD's wins are spread across rendering, encryption, string handling, and threading, making it the versatile choice. Intel's wins are concentrated in math, physics, and prime numbers, making it the specialized choice. For users who know their workloads lean toward floating-point calculations, Intel delivers. For everyone else, AMD's broader consistency across the benchmark suite makes it the safer recommendation. The launch MSRP difference of $176 versus $134 reflects AMD's newer process and higher boost clock, but the performance data shows the price gap is not matched by an equivalent performance gap in most tests.
