Intel Core i7-1195G7 vs Intel Core i7-5820K Comparison

The Intel Core i7-5820K and the Intel Core i7-1195G7 represent two very different philosophies from Intel, separated by nearly seven years of silicon evolution. The 5820K is a desktop Haswell-E part with six cores and a 140 W TDP, while the 1195G7 is a mobile Tiger Lake-U chip with four cores and a 28 W TDP. Their benchmark averages are nearly identical—the 5820K scores 2642, and the 1195G7 scores 2638, a delta of just 0.1%—yet their individual test results paint a clear picture of divergent strengths. The data shows that the newer mobile chip wins seven of the eight head-to-head tests, but the desktop part takes one decisive victory that reveals its unique character.

Where Each One Wins

The Intel Core i7-1195G7 dominates the Cinebench suite across every version tested. In Cinebench R15 multicore, it scores 887 against the 5820K’s 841, a 5.2% advantage. The margin holds in Cinebench R20, where the 1195G7 posts 3697 versus 3508, a 5.1% lead, and in R23, where it scores 8803 against 8354, another 5.1% gap. Single-core performance is similarly lopsided: the 1195G7 leads by 5.6% in R15 (125 vs 118), 5% in R20 (521 vs 495), and 5.1% in R23 (1242 vs 1179). The single-core story extends to Geekbench, where the 1195G7 scores 1584 against 1174, a commanding 25.9% advantage. This makes the 1195G7 the clear choice for any workload that relies on per-thread responsiveness or lightly threaded applications.

The Intel Core i7-5820K wins one benchmark decisively: Geekbench multicore. Here, it scores 5464 against the 1195G7’s 4248, a 28.6% margin. This is the only multicore test in the head-to-head where the 5820K comes out ahead, but it is a substantial one. The six-core, twelve-thread configuration scales better in this particular test than the 1195G7’s four-core, eight-thread layout. While the Cinebench multicore tests favor the 1195G7, Geekbench’s multicore workload apparently stresses the 5820K’s additional physical cores in a way that overcomes its older architecture. For users running applications that resemble that specific workload, the 5820K has a measurable edge.

Architecture Differences

The two processors are built on fundamentally different foundations. The 5820K uses the Haswell-E architecture on a 22 nm process node, with a die size of 356 mm² and 2,600 million transistors. Its six cores and twelve threads run at a base clock of 3.30 GHz and a boost clock of 3.60 GHz. The 1195G7 uses the Tiger Lake architecture with Willow Cove cores on a 10 nm process, with a die size of 144 mm². It has four cores and eight threads, running at a base clock of 2.90 GHz and a boost clock of 5.00 GHz. The 1195G7’s boost clock is dramatically higher, which explains its single-core dominance.

Cache configurations differ significantly. The 5820K has 64 KB of L1 and 256 KB of L2 per core, with 15 MB of shared L3. The 1195G7 has 80 KB of L1 and 1.25 MB of L2 per core, with 12 MB of shared L3. The newer chip’s larger per-core L2 cache is notable, but the 5820K has more total L3. Memory support also differs: the 5820K runs DDR4 with a quad-channel bus and 68.3 GB/s of bandwidth, while the 1195G7 supports DDR4, LPDDR4, and LPDDR4X over a dual-channel bus. The 5820K’s quad-channel memory bandwidth is a major architectural advantage for memory-intensive tasks, even if the benchmark averages do not always reflect it.

The 1195G7 includes integrated Iris Xe-LP Graphics G7 96EU, while the 5820K has no integrated graphics. The 5820K uses an Intel Socket 2011-3, whereas the 1195G7 uses Intel BGA 1449. The 5820K has an unlocked multiplier, while the 1195G7 is locked. PCIe support also differs: the 5820K offers Gen 3 with 28 lanes, while the 1195G7 offers Gen 4 with 16 lanes. The 1195G7 was released in 2021, while the 5820K dates to 2014. Both are end-of-life products.

The Verdict

The benchmark data supports a clear split. The Intel Core i7-1195G7 is the better processor for the vast majority of tasks. It wins all three Cinebench versions in both single-core and multicore, with consistent 5% to 5.6% margins. It also wins Geekbench single-core by a massive 25.9%. Its 5.00 GHz boost clock and newer architecture give it a decisive edge in responsiveness and lightly threaded performance. The 1195G7’s overall benchmark average of 2638 is nearly identical to the 5820K’s 2642, but it achieves that parity with fewer cores and at a fraction of the thermal envelope.

The Intel Core i7-5820K is the specialist choice. Its 28.6% Geekbench multicore win over the 1195G7 is the largest margin in any test, showing that its six cores and twelve threads still matter in certain workloads. Its quad-channel memory bus and 68.3 GB/s bandwidth are not matched by the 1195G7’s dual-channel setup. For users who prioritize that specific type of multicore performance and can tolerate a 140 W TDP, the 5820K has a legitimate case. However, the data shows that the 1195G7 wins seven out of eight head-to-head tests, making it the more balanced and generally capable processor. The 5820K is the pick for Geekbench-style multicore workloads; the 1195G7 is the pick for everything else.

These results are consistent across all three Cinebench versions, indicating that the 1195G7’s architectural efficiency and higher boost clock provide a steady advantage in rendering workloads.

Geekbench tells a different story. In Geekbench single-core, the 1195G7 wins decisively with 1584 against 1174, a 25.9% margin. This is the largest single-core gap in the entire comparison, underscoring the 1195G7’s strength in per-thread performance. However, in Geekbench multicore, the 5820K turns the tables with a 28.6% win, scoring 5464 against 4248. This is the only test the 5820K wins, but it is also the largest margin in either direction. The 5820K’s six cores and quad-channel memory clearly matter in this specific workload, allowing it to overcome the 1195G7’s per-core advantages.

Overall, the 1195G7 wins 7 of the 8 head-to-head benchmarks. The 5820K wins 1. The average benchmark scores are 2642 for the 5820K and 2638 for the 1195G7, with a delta of 0.1%. The data shows that the 1195G7 is the more consistent performer across the tested workloads, while the 5820K has a specific, narrow area of dominance in Geekbench multicore.
