Intel Core i7-5775C vs Intel Core i7-8809G Comparison

The Verdict

The data clearly favors the Intel Core i7-8809G for most compute-heavy workloads. It wins six of the eight head-to-head benchmarks, with every Cinebench win landing at approximately 9.7% (or 9.5% in one case) over the i7-5775C. The i7-5775C only counters in Geekbench, where it posts a multicore score 8% higher and a single-core score 2.8% higher.

For users running Cinebench-style rendering tasks, the i7-8809G is the pick. Its multicore advantage appears consistently across R15, R20, and R23. For Geekbench-centric workflows, the i7-5775C holds the edge, though the single-core margin is slim.

Buyers on a desktop platform with a Socket 1150 board should note the i7-5775C fits that socket and is multiplier-unlocked. The i7-8809G is a mobile part on Intel BGA 2270 and is locked. The i7-5775C also carries a launch MSRP of $366, while the i7-8809G has no recorded launch MSRP in the database.

Architecture Differences

Both processors share a 14 nm process node from Intel, but they come from different architectural families. The i7-8809G is built on Kaby Lake, specifically the Kaby Lake G codename, and targets the mobile segment. The i7-5775C is a Broadwell desktop part.

Core and thread counts are identical: 4 cores and 8 threads each. The i7-8809G has a higher boost clock at 4.20 GHz versus 3.70 GHz, though its base clock is lower at 3.10 GHz versus 3.30 GHz. The i7-8809G also carries a larger L3 cache at 8 MB shared against 6 MB shared on the i7-5775C. Both have the same per-core L1 and L2 allocations: 64 KB and 256 KB respectively.

Head-to-Head Benchmarks

The Cinebench suite paints a consistent picture. In Cinebench R15 multicore, the i7-8809G scores 724 against 660, a 9.7% lead. The single-core R15 result is 102 versus 93, also 9.7%. Moving to R20, the multicore score is 3017 versus 2750, again 9.7%, and single-core is 425 versus 388, a slightly narrower 9.5% edge. In R23, the multicore result is 7185 versus 6549, and single-core is 1014 versus 924, both at 9.7%. The i7-8809G wins six of eight tests, and in five of those six the margin is exactly 9.7%.

The Geekbench results flip the script. The i7-5775C scores 4989 in Geekbench multicore against 4590 for the i7-8809G, an 8% advantage. Single-core Geekbench favors the i7-5775C at 1441 versus 1401, a 2.8% edge.

What stands out is the consistency of the Cinebench gap versus the Geekbench reversal. The i7-8809G does not merely edge out the i7-5775C in rendering workloads; it holds nearly the same percentage lead across every Cinebench iteration. Meanwhile, the i7-5775C shows a meaningful multicore advantage in Geekbench that is larger than its single-core advantage, suggesting the workload characteristics matter more than raw clock speed.

The i7-8809G has a higher boost clock (4.20 GHz versus 3.70 GHz) and more L3 cache (8 MB versus 6 MB), which helps explain its Cinebench dominance. The i7-5775C, despite a lower boost clock, manages a higher Geekbench score, indicating that architectural differences and memory bandwidth (25.6 GB/s on the i7-5775C) can offset clock disadvantages in certain workloads.

Where Each One Wins

The i7-8809G is the clear winner for Cinebench-style rendering. It leads by 9.7% in multicore tests across R15, R20, and R23, and by 9.7% in single-core tests for R15 and R23, with R20 single-core at 9.5%. Users running CPU rendering, video encoding, or other heavily threaded workloads that resemble Cinebench should favor the i7-8809G. Its higher boost clock and larger L3 cache likely drive these gains.

The i7-5775C wins in Geekbench, both multicore (8% ahead) and single-core (2.8% ahead). This suggests it handles Geekbench's mixed workload profile better, possibly due to its desktop-oriented design, DDR3 memory with recorded 25.6 GB/s bandwidth, or architectural tuning in the Broadwell generation. Users whose applications correlate with Geekbench scores should consider the i7-5775C.

Platform considerations also split the two. The i7-8809G is a mobile chip on Intel BGA 2270, so it belongs in laptops or compact mobile systems. The i7-5775C is a desktop part for Intel Socket 1150, making it a fit for desktop builds. The i7-5775C is also unlocked, which matters for overclocking-oriented users, though the database does not record overclocked results.

The i7-8809G reaches the 48th percentile of all CPUs with an average score of 2307. Its nearest rivals include the Intel Core i5-10400H at 2303 (0.2% behind) and the Intel Xeon E-2134 at 2319 (0.5% ahead). The i7-5775C sits at the 47th percentile with 2224, near the Intel Core i7-8559U at 2225 (0% delta) and the Intel Xeon E5-4648 v3 at 2227 (0.1% ahead). The i7-8809G sits slightly higher in the overall database distribution.

For most users, the i7-8809G offers the stronger all-around benchmark profile, winning six of eight tests and holding a higher average score. The i7-5775C remains relevant specifically for Geekbench-style workloads and for desktop users who want an unlocked multiplier on Socket 1150.
