AMD Ryzen 7 5700G vs AMD Ryzen 7 5800 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall victory for the AMD Ryzen 7 5800, winning 17 of the 21 head-to-head benchmark comparisons, while the AMD Ryzen 7 5700G takes just 4 wins. The most dramatic gap appears in Cinebench R23, where the 5800 produces a multicore score of 21953 against the 5700G's 12830.5, a 71.1% advantage. Single-threaded Cinebench R23 is even more lopsided: the 5800 scores 3099 versus 1494, which translates to a 107.4% lead. These are not marginal differences; they indicate a fundamental performance tier separation in certain workloads.

Looking at 3DMark results, the 5800 consistently leads across all thread counts. The 16-thread test shows 7181 versus 6629, an 8.3% edge, while the max-threads test shows 7138 versus 6627, a 7.7% difference. The gap narrows at lower thread counts: 8-thread shows only a 0.8% lead (5692 versus 5648), and 2-thread shows a 2.1% lead (1795 versus 1758). This pattern suggests the 5800's advantage grows as more cores are utilized, which aligns with its cache configuration.

The Cinebench R15 results tell a similar story but with an interesting twist. Multicore shows a moderate 5% lead (2212 versus 2107), but singlecore shows a striking 28.7% gap (312 versus 242.5). This singlecore delta is far larger than any other single-threaded comparison in the dataset, which raises questions about the 5700G's efficiency under that specific workload.

PassMark results are more mixed. The 5800 wins floating point math by 0.6% (51588 versus 51296), integer math by 1.4% (92843 versus 91541), and multithread by 5.7% (25823 versus 24419). The 5700G counters with wins in data compression (318262 versus 316429, a 0.6% edge), data encryption (20325 versus 20021, a 1.5% edge), extended instructions (21847 versus 21297, a 2.5% edge), and random string sorting (33384 versus 32998, a 1.2% edge). The 5700G also shows a massive win in find prime numbers, but that is actually a loss: the 5800 scores 110 versus 59, meaning the 5800 is 86.4% faster in that test.

The physics test shows a 14.2% lead for the 5800 (1141 versus 999), which is substantial for a single metric. Overall, the benchmark data paints a clear picture: the 5800 dominates in most compute-heavy tasks, while the 5700G only squeaks ahead in a few specialized operations like compression and encryption.

Architecture Differences

Both processors share the Zen 3 architecture and are built on the same 7 nm process at TSMC, but they diverge significantly in implementation. The 5800 uses the Vermeer codename, while the 5700G uses Cezanne. This codename difference reflects a crucial design decision: the 5700G integrates Radeon Vega 8 graphics directly on the die, while the 5800 has no integrated graphics at all.

The transistor counts tell a dramatic story. The 5800 packs 4,150 million transistors on a 74 mm² die, while the 5700G contains 10,700 million transistors on a 180 mm² die. That is a 2.6x transistor count increase and a 2.4x die size increase for the 5700G, both attributable to the integrated GPU. The larger die and integrated graphics come with trade-offs.

Cache allocation is another major differentiator. The 5800 has 32 MB of shared L3 cache, while the 5700G has only 16 MB. Both have the same L1 (64 KB per core) and L2 (512 KB per core) configurations. The 5800's doubled L3 cache likely explains much of its performance advantage in compute-heavy benchmarks like Cinebench R23, where the 71.1% multicore gap and 107.4% singlecore gap are far larger than the clock speed differences would suggest.

Clock speeds are nearly identical: both have a 4.60 GHz boost clock, but the 5700G has a higher base clock at 3.80 GHz versus 3.40 GHz for the 5800. Both have a 65 W TDP, both support DDR4 memory with dual-channel configuration, and both deliver 51.2 GB/s memory bandwidth. The 5800 supports ECC memory, while the 5700G does not.

PCIe support also differs: the 5800 provides Gen 4 with 20 lanes (CPU only), while the 5700G provides Gen 3 with 16 lanes (CPU only). This means the 5800 offers both a newer PCIe generation and more lanes, which matters for expansion cards and high-speed storage. The 5800 was released on 2021-01-11, while the 5700G followed on 2021-04-12, a roughly three-month gap. Both are actively in production, both have unlocked multipliers, and both are desktop processors on AMD Socket AM4.

Where Each One Wins

The AMD Ryzen 7 5800 wins in scenarios demanding raw computational throughput. The Cinebench R23 results are the clearest indicator: a 71.1% multicore lead and a 107.4% singlecore lead make the 5800 the obvious choice for rendering, video encoding, scientific computing, and any workload that scales with cache size. The 86.4% advantage in find prime numbers further reinforces its strength in integer-heavy mathematical workloads. The 3DMark results across all thread counts show the 5800 is also better suited for gaming and graphics-adjacent tasks, assuming a discrete GPU is present.

The AMD Ryzen 7 5700G wins in a narrow set of specialized operations. Its 2.5% edge in extended instructions, 1.5% edge in data encryption, and 1.2% edge in random string sorting suggest it handles certain vectorized or cryptographic workloads slightly better, despite its smaller cache. The 0.6% lead in data compression is marginal but consistent. The 5700G's integrated Radeon Vega 8 graphics mean it is the only one of the two that can operate without a discrete GPU, making it suited for compact builds, office systems, or budget media centers where a separate graphics card is not desired.

The 5700G's higher base clock (3.80 GHz versus 3.40 GHz) may help in short-burst single-threaded tasks that do not sustain long enough to benefit from the 5800's larger cache. However, the benchmark data shows the 5800 still wins single-threaded tests in both 3DMark (1.9% lead) and PassMark (3.4% lead). The only clear use-case where the 5700G is preferable is when integrated graphics are required, as the 5800 cannot output video without a discrete GPU.

The Verdict

The benchmark data clearly favors the AMD Ryzen 7 5800 for anyone who can use a discrete GPU. Its 71.1% lead in Cinebench R23 multicore and 107.4% lead in Cinebench R23 singlecore are overwhelming, and its wins across 17 of 21 benchmarks show broad superiority. The 5800 also offers double the L3 cache, PCIe Gen 4 with more lanes, and ECC memory support, all at the same 65 W TDP and 4.60 GHz boost clock as the 5700G. For rendering, content creation, scientific workloads, and gaming with a dedicated graphics card, the 5800 is the clear choice from the data.

The AMD Ryzen 7 5700G is the only option of the two when integrated graphics are required. Its Radeon Vega 8 GPU allows full system functionality without a discrete card, which is essential for certain compact or low-power builds. The 5700G's benchmark wins in data compression, encryption, extended instructions, and random string sorting show it is not universally slower, but those margins are small (0.6% to 2.5%). The 5700G also has a higher base clock (3.80 GHz versus 3.40 GHz), which could benefit burst workloads, but the recorded benchmarks show the 5800 still wins all single-threaded tests.

The verdict is straightforward: the Ryzen 7 5800 is the superior processor in nearly every measurable way, and the Ryzen 7 5700G is only preferable when its integrated graphics are the deciding factor. The 5800's performance percentile versus all CPUs is 79, matching the 5700G's percentile, but its average benchmark score of 27535 versus 27051 confirms a small but consistent overall edge. For users with a discrete GPU, the 5800 is unambiguously the better buy based on this data. For users who need a GPU-free system, the 5700G is the only viable choice between these two.
