A: Across all recorded Cinebench tests, the Core i3-6320 averages 1085, and the Pentium Gold G6505 averages 1074. The delta is 0.2% against the Pentium, making them extremely close in overall metrics.

The Verdict

The data is unambiguous on one thing: the Intel Core i3-6320 is the faster processor in every recorded workload. Across the six Cinebench runs, it wins all six, with deltas ranging from 0.9% in single-core R20 to 1.9% in single-core R15. The margins are narrow, never exceeding 1.9%, but they are consistent. The Pentium Gold G6505, despite having a higher base clock (4.20 GHz vs 3.90 GHz), two fewer cores and a newer architecture, cannot overtake the Core i3-6320. Buyers picking between these two should note that the Core i3 wins every benchmark, but the Pentium Gold is still extremely close in raw output. The database records the Core i3-6320 as the winner in 6 of 6 head-to-head comparisons.

Head-to-Head Benchmarks

The two CPUs were recorded across six Cinebench runs, and the Core i3-6320 claimed victory in all of them. The largest margin comes in Cinebench R15 multi-core, where the Core i3 scores 378 against 374 (a 1.1% win). The same test in single-core mode showed the Core i3 ahead by 1.9%. In the R20 suite, the Core i3 wins multi-core by 1.0% and single-core by 0.9%. The R23 runs wrap up the set with the Core i3 ahead by 1.0% in multi-core and 1.0% in single-core. No test falls to the Pentium Gold G6505.

Specification Differences

The two chips diverge in several important specification fields. The Core i3-6320 uses the Intel Socket 1151 and the Skylake architecture, while the Pentium Gold G6505 uses Intel Socket 1200 and a Comet Lake core. The process node also varies: the Core i3 is built on a 14 nm process, the Pentium Gold on a 14 nm process. The Core i3-6320 is a 2-core, 4-thread part with a 3.90 GHz base clock and no boost clock. The Pentium Gold G6505 is also 2 cores and 4 threads, but it has a higher base clock of 4.20 GHz. TDP figures differ: the Core i3 is rated at 51 W, while the Pentium Gold is rated at 58 W.

Architecture Differences

The Core i3-6320 uses the Skylake microarchitecture (codename Skylake) and belongs to the Core i3 (Skylake) generation. It integrates an Intel HD 530 graphics solution. The Pentium Gold G6505 is built on Comet Lake (codename Comet Lake-R) and is part of the Pentium Gold (Comet Lake) generation. Its integrated graphics are handled by the UHD Graphics 630. The Core i3-6320 ships with 1,400 million transistors on a 150 mm² die, while the die size and transistor count for the Pentium Gold are not recorded in the database. Memory support is another split: the Core i3 supports DDR4 memory over a dual-channel bus with a recorded 34.1 GB/s of bandwidth. The Pentium Gold also supports DDR4, dual-channel memory, and it carries a higher 42.7 GB/s memory bandwidth. Neither part supports ECC memory. PCIe connectivity differs: the Core i3 has Gen 3 with 16 lanes (CPU only), and the Pentium Gold has Gen 3 with 16 lanes (CPU only). The Core i3-6320 was released on 2015-08-31; the Pentium Gold G6505 hit the market on 2021-03-15. The Core i3 part number is SR2H9, the Pentium Gold is SRH3V.
