Intel Core i3-10305 vs Intel Core i7-8809G Comparison

The Intel Core i7-8809G and Intel Core i3-10305 are both 4-core, 8-thread processors built on Intel's 14nm process, but they target completely different platforms and use cases. The data shows a clear overall winner in raw CPU performance: the i3-10305 wins all six head-to-head benchmark comparisons, with margins ranging from 8.1% to 8.4%. However, the i7-8809G is a mobile part with a Radeon RX Vega M GH integrated GPU, while the i3-10305 is a desktop chip with UHD Graphics 630. This means the choice depends heavily on whether you need a compact mobile solution with strong graphics or a desktop CPU with higher clock speeds and a newer architecture.

The Verdict

If you are building a desktop PC and prioritize pure CPU compute performance, the Intel Core i3-10305 is the definitive choice. It outperforms the i7-8809G in every single benchmark recorded, from Cinebench R15 single-core (111 vs 102) to Cinebench R23 multi-core (7828 vs 7185). The i3-10305 also has a higher base clock (3.80 GHz vs 3.10 GHz) and boost clock (4.50 GHz vs 4.20 GHz), making it the faster part for any CPU-bound workload on a desktop. Its percentile ranking of 47 vs the i7-8809G's 48 is nearly identical, but the i3's wins are consistent and meaningful.

The i7-8809G, on the other hand, is for a very specific niche: mobile systems where the integrated Radeon RX Vega M GH GPU provides far more graphics capability than the i3-10305's UHD Graphics 630. If you need a compact, all-in-one mobile package with decent gaming or GPU-accelerated compute, the i7-8809G makes sense despite its CPU deficit. The data shows it is not a bad CPU; it sits at the 48th percentile, with an average benchmark score of 2307, which is only 0.2% behind the Intel Core i5-10400H and 0.5% ahead of the Intel Xeon E-2134. But for a desktop user, the i3-10305 is strictly superior in processing power.

Architecture Differences

The two processors come from different Intel generations and are built for different sockets. The i7-8809G is based on the Kaby Lake architecture (codename Kaby Lake G) and uses the Intel BGA 2270 socket, which indicates a soldered, non-upgradeable mobile design. It belongs to the Core i7 (Kaby Lake-G) generation and was released on 2018-01-31. The i3-10305 uses the Comet Lake architecture (codename Comet Lake-R), fits the Intel Socket 1200 platform, and is part of the Core 10th Gen series, released on 2021-03-15.

Both chips use the same 14nm process node from Intel, and both have identical cache hierarchies: 64 KB L1 per core, 256 KB L2 per core, and 8 MB of shared L3. They also both support DDR4 memory and lack ECC support. The key architectural differences lie in their integrated graphics and platform features. The i7-8809G features a Radeon RX Vega M GH GPU, which is a discrete-class graphics solution integrated into the package, whereas the i3-10305 has the UHD Graphics 630. The i3-10305 also lists a dual-channel memory bus with 42.7 GB/s bandwidth and PCIe Gen 3 with 16 lanes (CPU only), while the i7-8809G's memory bus and PCIe details are not specified in the data. Neither processor has an unlocked multiplier.

FAQ

Q: How do their single-core performances compare?

A: The i3-10305 is consistently faster in single-core tests as well. It leads by 8.1% in Cinebench R15 single-core (111 vs 102), by 8.4% in R20 single-core (464 vs 425), and by 8.2% in R23 single-core (1105 vs 1014).

Q: Are they equally efficient in terms of power?

A: Both processors have a TDP of 65 watts, according to the data. However, the i7-8809G is a mobile part with a BGA socket, while the i3-10305 is a desktop part, so their thermal and power delivery contexts are different.

Q: Which processor has better integrated graphics?

A: The i7-8809G has a Radeon RX Vega M GH GPU, which is a far more capable graphics solution than the i3-10305's UHD Graphics 630. The data does not provide benchmark scores for these GPUs, but the naming and positioning indicate a significant difference in graphics capability.

Q: Can I use the i3-10305 in a laptop?

A: No. The i3-10305 uses the Intel Socket 1200, which is a desktop socket. The i7-8809G uses Intel BGA 2270, a mobile socket, so it is designed for soldered laptop or compact mobile applications.

Q: How do these CPUs compare to other processors in their respective performance tiers?

A: The i7-8809G has an average benchmark score of 2307, placing it 0.2% above the Intel Core i5-10400H (score 2303) and 0.6% below the AMD Ryzen 7 2700 (score 2320). The i3-10305's average score is 2264, which is 0.2% above the Intel Core i7-1068NG7 (score 2259) and 0.4% above the Intel Core i5-9400 (score 2254).

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Core i3-10305 wins all six recorded comparisons. The largest margin is in Cinebench R20 single-core, where the i3 scores 464 against the i7-8809G's 425, a delta of -8.4% from the i7's perspective. The smallest margin is 8.1%, seen in both Cinebench R15 multi-core (788 vs 724) and R15 single-core (111 vs 102).

In Cinebench R20 multi-core, the i3-10305 scores 3287 versus 3017 for the i7-8809G, an 8.2% lead. Cinebench R23 multi-core shows a similar 8.2% gap, with the i3 at 7828 and the i7 at 7185. Cinebench R23 single-core also lands at 8.2%, with scores of 1105 and 1014 respectively.

The i7-8809G does have a Geekbench result in the data — a multi-core score of 4590 and a single-core score of 1401 — but the i3-10305 has no corresponding Geekbench scores provided, so no direct comparison is possible for that test. Overall, the i3-10305's win count is 6 out of 6 head-to-head tests, with zero wins for the i7-8809G.

Where Each One Wins

The i3-10305 wins in every CPU compute category where data exists. For desktop users running multi-threaded productivity workloads like video rendering, 3D modeling, or software compilation, the i3-10305 is the faster choice. Its Cinebench R23 multi-core score of 7828 versus 7185 means it completes these tasks roughly 8% quicker. Similarly, for single-threaded performance — which matters for older games, spreadsheet calculations, or lightly-threaded applications — the i3's higher boost clock of 4.50 GHz gives it an edge, as shown by its 8.1% to 8.4% lead across all single-core tests. This is a straightforward recommendation for a desktop build.

The i7-8809G's winning scenario is not in CPU benchmarks but in its integrated graphics and mobile form factor. With the Radeon RX Vega M GH, it offers a level of GPU performance that the UHD Graphics 630 cannot match. If you are designing a compact media center, a small-form-factor gaming laptop, or a portable workstation where you cannot install a discrete GPU, the i7-8809G's integrated graphics make it the more practical choice, despite being 8% slower in CPU tasks. Its market segment is explicitly Mobile, and its BGA 2270 socket confirms it is meant for systems where the CPU is soldered directly to the board. For those who need a self-contained mobile package with strong graphics, the i7-8809G is the pick. For everyone else who values raw CPU throughput, the i3-10305 is the clear winner.
