AMD Ryzen 3 PRO 8300G vs Intel Core 5 320 Comparison

Head-to-Head Benchmarks

The benchmark data presents a split profile. The AMD Ryzen 3 PRO 8300G wins 5 of the 17 recorded comparisons, while the Intel Core 5 320 wins 12. The most dramatic result is in Cinebench R23 multi-core, where the AMD chip scores 12359 against 6197 for Intel, a 99.4% advantage. This single result dominates the multi-threaded narrative. In Cinebench R15 multi-core, AMD also leads, scoring 1245 versus 1054, a 18.1% margin.

The Intel Core 5 320, however, takes the single-core crown across every Cinebench iteration. In Cinebench R15 single-core, Intel scores 276 versus 175, a 36.6% gap. The R20 single-core test shows Intel at 771 against 732, a 5.1% edge, and R23 single-core shows 1926 versus 1744, a 9.4% advantage. The PassMark single-thread result aligns with this pattern: Intel scores 4045, AMD 3550, a 12.2% deficit for the AMD part.

The floating-point and encryption workloads heavily favor Intel. PassMark floating point math shows Intel at 42440 versus 23374, a 44.9% lead. Data encryption favors Intel 10984 to 8607, a 21.6% margin. Prime number finding is also Intel-dominated, 110 versus 47, a 57.3% difference. Extended instructions go to Intel 13262 to 11451, a 13.7% edge.

AMD fights back in integer-heavy and compression workloads. PassMark integer math scores 37292 for AMD versus 32323 for Intel, a 15.4% win. Data compression is nearly even, AMD at 150567 against 148779, a 1.2% margin. Random string sorting favors AMD 19703 to 18038, a 9.2% difference.

The multi-thread PassMark result goes to Intel, 15450 versus 13368, a 13.5% margin, despite AMD's Cinebench R23 multi-core dominance. This inconsistency suggests workload-specific scheduling and memory effects. The physics test also favors Intel, 1221 versus 772, a 36.8% gap.

Architecture Differences

The AMD Ryzen 3 PRO 8300G uses the Zen 4 architecture on TSMC's 4 nm process, with a Phoenix2 codename. It contains 4 cores and 8 threads, reflecting simultaneous multi-threading. The Intel Core 5 320 uses the Wildcat Lake codename on Intel's 3 nm process, with 6 cores and 6 threads, meaning no hyper-threading. The node difference favors Intel by one nanometer step, but the core count favors Intel at 6 versus 4.

Cache hierarchies diverge sharply. AMD provides 64 KB of L1 per core and 1 MB of L2 per core, with 8 MB of shared L3. Intel lists 192 KB of L1 total, 2.5 MB of L2 total, and 6 MB of shared L3. The AMD chip also reports a die size of 137 mm² and 20,900 million transistors, while the Intel database entry lacks both transistor count and die size.

Memory support differs in channel configuration. AMD uses dual-channel DDR5 with a recorded bandwidth of 83.2 GB/s and supports ECC memory. Intel supports DDR5 and LPDDR5X but runs single-channel, with a bandwidth of 59.7 GB/s and no ECC support. The PCIe lanes also differ: AMD offers Gen 4 with 14 lanes (CPU only), while Intel offers Gen 4 with 6 lanes (CPU only).

Integrated graphics differ in branding and execution units. AMD pairs the Radeon 740M, while Intel uses Xe3 Graphics with 2 Xe cores. The socket and market segment also differ: AMD sits in an AM5 desktop socket, Intel in a BGA 1516 mobile package. The Intel part has a launch MSRP of $340, while the AMD entry has no recorded MSRP.

The Verdict

The data points to distinct usage profiles. The AMD Ryzen 3 PRO 8300G delivers a 99.4% multi-core Cinebench R23 advantage and leads in integer math, data compression, and random string sorting. The Intel Core 5 320 counters with wins in single-core tests, floating-point math, encryption, prime finding, and the PassMark multi-thread suite. The overall average benchmark score favors Intel: 18023 versus 17278, a difference that places Intel at the 72nd percentile and AMD at the 71st percentile.

The Intel part also appears in the database with a launch MSRP of $340, while AMD has no recorded launch price. The AMD chip matches closely with rivals like the Intel Core i5-12450H (0.2% delta) and the AMD Ryzen 3 210 (-0.2% delta). The Intel part sits near the AMD Ryzen 5 1600 (0.2% delta) and the Intel Core 5 120U (0.7% delta).

Where Each One Wins

The AMD Ryzen 3 PRO 8300G wins in scenarios that stress multi-core rendering and integer processing. Its Cinebench R23 multi-core score of 12359 is nearly double the Intel score, so content creation workloads that scale across threads will favor AMD. The 15.4% integer math lead and the 9.2% random string sorting advantage suggest text processing and general integer computation benefit from the AMD design. The 1.2% data compression edge, while narrow, adds to the AMD column.

The Intel Core 5 320 wins in single-threaded and floating-point scenarios. The 12.2% single-thread PassMark lead and the 9.4% Cinebench R23 single-core lead point to lightly threaded applications favoring Intel. The 44.9% floating-point math margin and the 21.6% encryption advantage suggest scientific and cryptographic workloads run better on Intel. The 57.3% prime number finding lead reinforces this pattern. The 36.8% physics test advantage and the 13.5% PassMark multi-thread lead indicate that certain parallel workloads also prefer Intel.

The mobile versus desktop split is reflected in power and bandwidth. Intel's 15 W TDP and single-channel 59.7 GB/s bandwidth suit low-power mobile designs, while AMD's 65 W TDP and dual-channel 83.2 GB/s bandwidth suit desktop builds where power and memory bandwidth are less constrained. The 6-lane PCIe Gen 4 on Intel versus 14-lane on AMD further separates the two in expansion capability.
