AMD Ryzen 3 3100 vs Intel Core i7-7700T Comparison

The AMD Ryzen 3 3100 and Intel Core i7-7700T are both 4-core, 8-thread desktop processors, but benchmark data shows they occupy very different performance tiers. The Ryzen 3 3100 wins every single head-to-head benchmark in the data set, with a perfect 4-0 record. Its average benchmark score of 2055 places it in the 46th percentile of all CPUs, while the i7-7700T’s average score of 2039 sits at the 45th percentile. The Ryzen 3 3100 is the clear choice for anyone prioritizing raw compute performance, as it leads by margins ranging from 11.8% in Geekbench single-core to a massive 95.6% in Cinebench R15 single-core. The i7-7700T, however, is not without merit: its 35W TDP and integrated HD 630 graphics make it a compelling option for low-power, compact builds where the Ryzen 3 3100’s lack of integrated graphics is a disqualifier.

The Verdict

The data paints a one-sided picture. The AMD Ryzen 3 3100 outperforms the Intel Core i7-7700T in every benchmark category recorded, making it the superior choice for workloads that demand processing power. The largest gap appears in Cinebench R15 single-core, where the Ryzen 3 3100 scores 178 versus the i7-7700T’s 91, a 95.6% advantage. This suggests the AMD chip’s Zen 2 architecture delivers dramatically better single-threaded efficiency. In multi-threaded tasks, the Ryzen 3 3100 also leads decisively, scoring 991 in Cinebench R15 multi-core against 646 for the Intel part, a 53.4% difference. Geekbench results confirm the trend, with the Ryzen 3 3100 ahead by 24.4% in multi-core and 11.8% in single-core.

The i7-7700T’s saving grace is its 35W TDP, which is nearly half of the Ryzen 3 3100’s 65W. This makes the Intel processor ideal for silent, low-power, or thermally constrained systems where performance per watt trumps absolute performance. The i7-7700T also includes integrated HD 630 graphics, a feature completely absent from the Ryzen 3 3100. For users who need a basic display output without a discrete GPU, the Intel chip is the only viable option in this matchup. However, for anyone building a system with a dedicated graphics card and seeking maximum compute throughput, the Ryzen 3 3100 wins outright based on the benchmark scores.

Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD Ryzen 3 3100 uses the Zen 2 architecture built on a 7nm process node from TSMC, codenamed Matisse. It packs 3,800 million transistors into a 74 mm² die. The Intel Core i7-7700T, in contrast, uses the older Kaby Lake architecture on Intel’s 14nm process. The process node difference is stark — 7nm versus 14nm — which explains the Ryzen 3 3100’s superior performance per clock and energy efficiency despite its higher TDP.

Cache hierarchies also differ significantly. Both processors have 64 KB of L1 cache per core, but the Ryzen 3 3100 has 512 KB of L2 cache per core, double the i7-7700T’s 256 KB per core. The L3 cache difference is even more pronounced: the Ryzen 3 3100 has a 16 MB shared L3 cache, while the i7-7700T is limited to 8 MB. These cache advantages likely contribute to the Ryzen 3 3100’s dominance in memory-sensitive workloads. The Intel chip does include integrated graphics (HD 630), whereas the AMD chip has none. The Ryzen 3 3100 also features a newer PCIe Gen 4 interface with 16 lanes, compared to the i7-7700T’s PCIe Gen 3 with the same lane count.

Head-to-Head Benchmarks

The benchmark data reveals consistent and often overwhelming AMD superiority. Starting with Cinebench R15 multi-core, the Ryzen 3 3100 scores 991 against the i7-7700T’s 646, a 53.4% lead. This test stresses all cores simultaneously, and the Ryzen 3 3100’s higher 3.60 GHz base and 3.90 GHz boost clocks, combined with its larger caches, deliver a decisive win. The single-core Cinebench R15 result is even more lopsided: 178 for the Ryzen 3 3100 versus 91 for the i7-7700T, a jaw-dropping 95.6% margin. This near-doubling of single-threaded performance highlights the generational leap in architectural efficiency between Zen 2 and Kaby Lake.

Geekbench results are closer but still favor AMD. In multi-core, the Ryzen 3 3100 scores 4898 versus 3938 for the i7-7700T, a 24.4% advantage. Single-core Geekbench shows a more modest 11.8% lead, with scores of 1395 and 1248 respectively. The Ryzen 3 3100 also has additional benchmark data from 3DMark tests, though no direct comparison exists for the i7-7700T in those metrics. The 3DMark scores range from 660 in single-thread to 2972 in 8-thread and 2970 in max-thread tests, indicating strong scaling across thread counts. The i7-7700T has no corresponding 3DMark entries in the data, making direct comparison impossible, but its Cinebench and Geekbench deficits suggest it would likely trail in those tests as well.

Specification Differences

The processors differ on nearly every specification that matters. The AMD Ryzen 3 3100 has a base clock of 3.60 GHz and a boost clock of 3.90 GHz, while the Intel Core i7-7700T runs at 2.90 GHz base and 3.80 GHz boost. The TDP difference is substantial: 65W for AMD versus 35W for Intel. Socket compatibility is entirely separate, with the Ryzen 3 3100 using AMD Socket AM4 and the i7-7700T using Intel Socket 1151. Memory bandwidth is another differentiator, with the Ryzen 3 3100 supporting 51.2 GB/s versus 38.4 GB/s for the Intel chip, both over dual-channel DDR4.

The Ryzen 3 3100 has an unlocked multiplier, making it overclockable, while the i7-7700T is locked. PCIe support differs by generation: Gen 4 for AMD versus Gen 3 for Intel. The i7-7700T includes integrated HD 630 graphics; the Ryzen 3 3100 has none. Release dates are separated by over three years, with the i7-7700T launching in January 2017 and the Ryzen 3 3100 in April 2020. The AMD chip has a launch MSRP of $99, while the Intel chip’s launch price is not recorded. Both processors are currently marked as Active in production status. The Ryzen 3 3100 has a higher transistor count (3,800 million versus unknown for Intel) and a smaller die size (74 mm² versus unknown), but the i7-7700T’s part number (SR339) is documented while the AMD chip’s is 100-000000284.

Where Each One Wins

The AMD Ryzen 3 3100 wins in every performance category measured, but its victories are most pronounced in single-threaded and moderately threaded workloads. The 95.6% Cinebench R15 single-core advantage suggests the Ryzen 3 3100 is exceptional for applications that rely on high per-core performance, such as older games, spreadsheet calculations, or lightly threaded productivity tools. The 53.4% multi-core lead in Cinebench R15 indicates strong performance in video encoding, 3D rendering, and compilation tasks that scale across all eight threads. The 11.8% Geekbench single-core lead and 24.4% multi-core lead confirm broad superiority across mixed workloads. The Ryzen 3 3100’s higher clocks (3.60/3.90 GHz versus 2.90/3.80 GHz), larger L2 and L3 caches, and faster memory bandwidth (51.2 GB/s versus 38.4 GB/s) all contribute to its dominance.

The Intel Core i7-7700T wins in power efficiency and integrated graphics. Its 35W TDP makes it the obvious choice for fanless or passively cooled systems, small form factor builds, or any scenario where heat dissipation is a challenge. The integrated HD 630 graphics allow for a working system without a discrete GPU, which is critical for basic office tasks, media playback, or troubleshooting. The i7-7700T’s lower power draw also makes it attractive for always-on systems like home servers or network-attached storage, where the Ryzen 3 3100’s higher power consumption could be a drawback. For users who prioritize absolute performance, the Ryzen 3 3100 is the clear winner; for those who value efficiency and simplicity, the i7-7700T’s lower power envelope and built-in graphics make it a practical alternative.
