AMD Ryzen 3 2300U vs Intel Core i7-860 Comparison

Intel Core i7-860 and AMD Ryzen 3 2300U occupy nearly identical positions in the overall performance hierarchy, with the desktop Intel chip from 2009 posting an average benchmark score of 886 against the mobile AMD part's 880. The data shows a razor-thin 0.7% gap in average scores, yet the underlying benchmark results tell a more complex story about how these two very different processors approach work. The Intel Core i7-860 ranks at the 24th percentile of all CPUs, while the Ryzen 3 2300U sits at the 23rd percentile, placing both firmly in the same performance tier despite nine years of architectural evolution separating them.

Head-to-Head Benchmarks

The only directly comparable benchmark in the data is Cinebench R15 multi-core, and the results are decisive. The AMD Ryzen 3 2300U scores 422.5 against the Intel Core i7-860's 259, a 38.7% advantage for the AMD part. This is a substantial margin, indicating that in this specific rendering workload, the Ryzen 3 2300U delivers roughly 1.6 times the throughput of the older Intel processor. The magnitude of this win is striking given that the i7-860 has eight threads to the Ryzen's four, meaning the AMD chip achieves this lead while managing half the thread count.

The Intel Core i7-860 does not win any head-to-head benchmark, but its benchmark suite includes tests the Ryzen 3 2300U does not share. The i7-860 posts Cinebench R20 multi-core and single-core scores of 1081 and 152, respectively, and in Cinebench R23 it reaches 2574 multi-core and 363 single-core. The Ryzen 3 2300U counters with a Cinebench R15 single-core score of 79, plus Geekbench multi-core and single-core results of 2234 and 783. Without overlapping tests beyond R15 multi-core, the data prevents a full apples-to-apples comparison, but the one shared metric clearly favors AMD.

The average benchmark scores of 886 versus 880 suggest the two chips are nearly equivalent overall, yet this masks the distribution of wins. The Ryzen 3 2300U's 38.7% lead in Cinebench R15 multi-core is the only direct comparison available, and it is a decisive one. The Intel part's additional benchmark entries (R20 and R23) show it can still produce competitive numbers in newer Cinebench versions, but those results cannot be directly weighed against the AMD part. What the data does reveal is that in the one workload where both processors were tested under identical conditions, the newer AMD architecture wins by a wide margin.

Where Each One Wins

The AMD Ryzen 3 2300U wins in multi-threaded rendering performance, as demonstrated by its Cinebench R15 multi-core score of 422.5 versus the i7-860's 259. This suggests the Ryzen 3 2300U is the stronger choice for tasks that fully utilize all available cores, despite having only four threads compared to the Intel chip's eight. The Ryzen's 14 nm Zen architecture and 4 MB of L3 cache appear to compensate for its lower thread count, delivering superior throughput in this benchmark.

The Intel Core i7-860 wins in thread count and cache capacity, with 8 threads and 8 MB of shared L3 cache versus the Ryzen's 4 threads and 4 MB. These specifications do not translate into a benchmark win in the shared test, but they indicate the i7-860 could perform relatively better in workloads that scale with thread availability or benefit from larger pooled cache. The Intel chip also has a higher boost clock at 3.47 GHz versus the Ryzen's 3.40 GHz, a marginal advantage that might matter in lightly threaded tasks, though the Ryzen's single-core Cinebench R15 score of 79 cannot be directly compared to anything the Intel part offers.

For single-threaded performance, the data is inconclusive because the two chips were tested with different benchmark suites. The Ryzen 3 2300U's Geekbench single-core score of 783 stands alone, while the i7-860's Cinebench R23 single-core score of 363 cannot be mapped onto that scale. What the data does show is that the Ryzen 3 2300U holds a clear edge in the one multi-core test both share, which is the most reliable signal available.

Specification Differences

The two processors differ across nearly every major specification. The Intel Core i7-860 has 8 threads, while the AMD Ryzen 3 2300U has 4. Base clocks are 2.80 GHz for the Intel part and 2000.00 MHz (2.00 GHz) for the AMD part, with boost clocks of 3.47 GHz and 3.40 GHz, respectively. TDP ratings diverge sharply: the i7-860 draws 95 watts, while the Ryzen 3 2300U draws only 15 watts, reflecting their desktop versus mobile market segments.

Memory support differs completely, with the Intel chip using DDR3 and the AMD chip using DDR4. The AMD part has a stated memory bandwidth of 38.4 GB/s, while the Intel part lists none. PCIe support also differs: the i7-860 has Gen 2 with 16 lanes (CPU only), while the Ryzen 3 2300U has Gen 3 with 8 lanes (CPU only). Socket types are incompatible, with the Intel chip using Socket 1156 and the AMD chip using Socket FP5.

The market segments and production statuses are opposite: the Intel Core i7-860 is a desktop part that is end-of-life, released on 2009-09-07, while the AMD Ryzen 3 2300U is a mobile part that is active, released on 2018-01-07. The Intel chip has no integrated graphics, while the AMD chip includes Radeon Vega 6 graphics. Cache hierarchies also differ, with the Intel part offering 64 KB L1 and 256 KB L2 per core plus 8 MB shared L3, versus the AMD part's 96 KB L1 and 512 KB L2 per core plus 4 MB shared L3.

Architecture Differences

The architectural gap between these two chips spans nearly a decade of semiconductor evolution. The Intel Core i7-860 uses the Nehalem architecture with the Lynnfield codename, built on a 45 nm process node at Intel's foundry. It packs 774 million transistors into a 296 mm² die. The AMD Ryzen 3 2300U uses the Zen architecture with the Raven Ridge codename, built on a 14 nm process node at GlobalFoundries. It crams 4,950 million transistors into a 210 mm² die — a 6.4x increase in transistor count on a 29% smaller die.

These architectural differences translate into divergent design philosophies. The Intel chip relies on its 8 MB of shared L3 cache to feed its 8 threads, while the AMD chip uses a smaller 4 MB L3 but larger per-core L1 and L2 caches (96 KB and 512 KB versus 64 KB and 256 KB). The Ryzen 3 2300U integrates Radeon Vega 6 graphics, while the i7-860 has no integrated graphics at all. The AMD part also features a newer PCIe Gen 3 interface, though with half the lane count of the Intel chip's Gen 2 implementation.

The manufacturing differences are stark: the 45 nm Intel process versus the 14 nm AMD process represents a 3.2x linear shrink. This allows the Ryzen 3 2300U to deliver competitive performance at 15 watts versus 95 watts — a 6.3x efficiency improvement. The Ryzen 3 2300U's 38.4 GB/s of memory bandwidth over DDR4 also contrasts with the i7-860's DDR3 support, which has no listed bandwidth in the data. These architectural choices explain why the AMD part wins the shared benchmark despite having half the threads.

The Verdict

The data directs different buyers toward each chip. The AMD Ryzen 3 2300U is the clear performance winner in the only directly comparable benchmark, posting a 38.7% higher Cinebench R15 multi-core score than the Intel Core i7-860. For anyone prioritizing multi-threaded rendering workloads, the Ryzen 3 2300U is the superior choice, and its 15-watt TDP makes it dramatically more power-efficient than the 95-watt Intel part. The Ryzen 3 2300U also brings modern features like DDR4 support, PCIe Gen 3, and integrated graphics, making it a more complete package.

The Intel Core i7-860, despite being end-of-life and from 2009, still holds its own in aggregate benchmark scores. Its 886 average score edges out the Ryzen 3 2300U's 880, and its 8 threads and larger 8 MB L3 cache could benefit workloads that exploit high thread counts or large pooled caches. The Intel chip also has a marginally higher boost clock at 3.47 GHz versus 3.40 GHz. However, the Intel part offers no integrated graphics, uses older DDR3 memory, and consumes 6.3 times more power.

For a new build or a mobile system, the AMD Ryzen 3 2300U is the obvious pick based on this data. It wins the shared benchmark decisively, offers modern memory and I/O standards, and does so at a fraction of the power draw. For someone specifically targeting workloads that scale with thread count or need large L3 cache, the Intel Core i7-860's 8 threads and 8 MB of cache might provide an edge, though the data does not include a benchmark that proves this advantage. The Ryzen 3 2300U's active production status and mobile market positioning also suggest better long-term support. Based strictly on the numbers, the Ryzen 3 2300U is the stronger processor for most applications, with the i7-860 appealing only to niche thread-heavy use cases where its cache and thread count could matter more than the shared benchmark suggests.
