AMD Ryzen 3 5300G vs Intel Core i7-7800X Comparison

The Intel Core i7-7800X and AMD Ryzen 3 5300G present a striking case of generational divergence. While the older Intel part fields six cores and twelve threads against the AMD's four cores and eight threads, the benchmark data reveals a near-total reversal of expected outcomes. The AMD Ryzen 3 5300G wins seven of the eight head-to-head comparisons, yet the Intel part secures a decisive victory in Geekbench multi-core, illustrating that workload type, not core count alone, dictates the winner.

Head-to-Head Benchmarks

The Cinebench suite shows an extraordinarily tight race, with the AMD Ryzen 3 5300G edging out the Intel Core i7-7800X in every single test. In Cinebench R15 multi-core, the scores are 1114 for AMD versus 1113 for Intel, a negligible delta of -0.1%. The single-core R15 test repeats this pattern: 157 for AMD versus 156 for Intel, a -0.6% delta. This margin expands slightly in Cinebench R20, where AMD scores 4645 against Intel's 4638, a -0.2% difference, and the single-core test shows 655 versus 654. The trend continues in Cinebench R23, with AMD posting 11060 multi-core and 1561 single-core against Intel's 11044 and 1559, each a -0.1% delta.

These sub-one-percent margins are remarkable given the structural disparity: the Intel part has 50% more cores and threads, yet cannot convert that hardware advantage into a Cinebench win. The data suggests that the Zen 3 architecture's higher instructions-per-clock and superior single-thread efficiency fully compensate for the core deficit in this rendering workload. For practical purposes, these two processors are functionally identical in Cinebench, with deltas so small they fall within normal run-to-run variance.

The Geekbench results break the deadlock decisively. In Geekbench multi-core, the Intel Core i7-7800X scores 6144 against AMD's 5467, a substantial 12.4% lead for Intel. This is the only benchmark where the older part wins, and it does so convincingly. The extra two cores and four threads finally assert themselves in a workload that scales well with parallel resources. However, the single-core Geekbench test flips the script dramatically: AMD scores 1768 versus Intel's 1352, giving AMD a 23.5% advantage. This is the largest margin in either direction across all tests, highlighting the massive single-thread efficiency gap between Skylake-X and Zen 3.

Averaging the benchmark scores yields 3333 for Intel and 3303 for AMD, placing the Intel part a mere 0.9% ahead of its rival in overall average. Both processors sit at the 54th percentile of all CPUs, indicating they occupy the same performance tier despite their architectural differences.

A: The Intel Core i7-7800X has an average benchmark score of 3333, which is 0.9% higher than AMD's 3303. However, both processors rank at the 54th percentile of all CPUs.

Q: How do these processors compare to their nearest rivals?

A: The Intel part's nearest rival is the AMD Ryzen 3 5300G itself, with a delta of 0.9%. AMD's nearest rival is the AMD Ryzen 5 PRO 2600 at an exact 0.0% delta, followed by the Intel Core i5-11400T at -0.2%.

Architecture Differences

The Intel Core i7-7800X is built on the Skylake-X architecture, a 14nm design from Intel, while the AMD Ryzen 3 5300G uses the Zen 3 architecture on TSMC's 7nm process. This process difference is significant: AMD's 7nm node allows for higher transistor density, with the Ryzen 3 packing 10,700 million transistors into an 180 mm² die. The Intel part does not have published transistor or die size data in the available specifications.

The core configurations differ fundamentally. Intel offers six cores and twelve threads, while AMD provides four cores and eight threads. Both have 64 KB of L1 cache per core, but the L2 cache differs: Intel provides 1 MB per core versus AMD's 512 KB per core. L3 cache totals are similar, with Intel at 8.25 MB shared and AMD at 8 MB.

Memory architecture diverges sharply. Intel supports quad-channel DDR4 with a theoretical bandwidth of 76.8 GB/s, while AMD uses dual-channel DDR4 at 51.2 GB/s. Both support DDR4, and neither supports ECC memory. PCIe capabilities also differ: Intel offers 28 Gen 3 lanes, while AMD provides 16 Gen 3 lanes.

A major feature difference is integrated graphics. The AMD Ryzen 3 5300G includes Radeon Vega 6 integrated graphics, while the Intel Core i7-7800X has no integrated graphics at all. This makes the AMD part a complete system-on-chip, whereas the Intel processor requires a discrete GPU. The AMD part is manufactured by TSMC, while Intel uses its own foundry.

Specification Differences

The clock speeds favor AMD significantly. The Ryzen 3 5300G has a base clock of 4.00 GHz and a boost clock of 4.20 GHz, compared to Intel's 3.50 GHz base and 4.00 GHz boost. This gives AMD a higher operating frequency across the board.

Power consumption shows a dramatic split. The Intel Core i7-7800X has a TDP of 140 watts, while the AMD Ryzen 3 5300G draws only 65 watts. This represents a 53.6% reduction in thermal design power for AMD, which is substantial for system cooling and power supply requirements.

Socket compatibility differs entirely. Intel uses Socket 2066, while AMD uses Socket AM4. These are not interchangeable platforms, requiring different motherboards. The memory bus width also differs, with Intel supporting quad-channel and AMD dual-channel, as previously noted.

The production status and release dates tell a story of product lifecycle. The Intel part was released on 2017-06-25 and is now end-of-life, while the AMD part was released on 2021-04-12 and remains active. The Intel part has a launch MSRP of $383, while AMD's launch MSRP is not listed. Both processors have unlocked multipliers for overclocking.

Where Each One Wins

The AMD Ryzen 3 5300G is the clear winner for single-threaded performance and efficiency. Its 23.5% lead in Geekbench single-core, combined with wins in every Cinebench single-core test, makes it the superior choice for lightly-threaded applications such as general productivity, web browsing, and legacy software that cannot utilize multiple cores effectively. The 65-watt TDP also makes it suitable for compact builds with modest cooling requirements. The inclusion of Radeon Vega 6 integrated graphics means it can function as a complete system without a discrete GPU, which is a decisive advantage for basic desktop use or media center builds.

The Intel Core i7-7800X wins specifically in Geekbench multi-core, where its 12.4% advantage reflects the benefit of two additional cores and four additional threads. This makes it the better choice for workloads that scale well with parallel execution, such as certain productivity suites and content creation tools that are optimized for high core counts. The quad-channel memory interface, providing 76.8 GB/s of bandwidth versus AMD's 51.2 GB/s, also gives Intel an advantage in memory-bandwidth-sensitive applications, even though this is not directly measured in the provided benchmarks.

The average benchmark scores place Intel 0.9% ahead overall, but this masks the workload-specific nature of the results. For users prioritizing raw multi-threaded throughput in Geekbench-style workloads, the Intel part offers a meaningful edge. For users prioritizing single-thread speed, power efficiency, and integrated graphics, the AMD part is overwhelmingly superior. The 54th percentile ranking for both processors confirms that they are mid-pack performers in the broader CPU landscape, with the choice between them depending entirely on whether the user's primary workloads align with Intel's multi-core strength or AMD's architectural efficiency advantages.
