Intel Core i7-8809G vs Intel Xeon D-1557 Comparison

The Intel Core i7-8809G and Intel Xeon D-1557 are fundamentally different processors, and the benchmark data makes that clear. The Xeon D-1557 wins every single head-to-head benchmark in this comparison, yet the two chips land within 1% of each other in average benchmark score and hold nearly identical percentile rankings. That means the i7-8809G is not a weak performer; it’s simply being compared against a chip with more cores and a different design philosophy, and the data shows the Xeon’s lead is consistent but not overwhelming.

Head-to-Head Benchmarks

The Xeon D-1557 sweeps all six head-to-head tests, but the margins tell the real story. In Cinebench R15 multicore, the Xeon scores 795 against the i7-8809G’s 724, a delta of -8.9% for the i7. The single-core R15 result is nearly identical, with the Xeon at 112 and the i7 at 102, again an 8.9% gap. That pattern holds across every Cinebench iteration: R20 multicore shows 3314 versus 3017 (-9%), and R20 single-core shows 467 versus 425 (-9%). R23 multicore repeats the 9% deficit with 7892 versus 7185, and R23 single-core closes at 1114 versus 1014, also -9%.

The consistency is striking. Every benchmark, regardless of workload type or version, produces roughly the same 9% delta. This suggests the Xeon’s advantage is structural, not workload-specific. It wins by a steady margin in both single-threaded and multi-threaded tests, meaning it’s not just a core-count advantage. In fact, the single-core results are where the Xeon’s lead is most surprising, since the i7-8809G has a much higher boost clock. The i7’s boost clock of 4.20 GHz should theoretically give it an edge in single-threaded workloads, but the Xeon’s 2.10 GHz boost still manages to win by 9%. That points to the Xeon’s Broadwell architecture being more efficient per clock, or the i7’s Kaby Lake-G design being hampered by its integrated graphics or thermal constraints.

The i7-8809G does have one benchmark the Xeon cannot match: Geekbench. The i7 scores 4590 in Geekbench multicore and 1401 in single-core, while the Xeon D-1557 has no Geekbench results in this data set. That’s a meaningful omission because it means the Xeon’s lead is only demonstrated in Cinebench tests. In real-world applications that resemble Geekbench’s workload mix, the i7 could close the gap or even overtake the Xeon. But within the provided head-to-head data, the Xeon wins every test, and the average benchmark score reflects that dominance: the i7’s average is 2307, while the Xeon’s is 2282, a difference of only 1.1% in the i7’s favor.

That average score is where the story gets nuanced. The i7-8809G has a higher average benchmark score (2307 versus 2282) despite losing every Cinebench test, because its Geekbench scores are strong enough to pull the average up. The Xeon’s nearest rival is the Intel Xeon E5-2629 v3 with a delta of 0%, meaning the D-1557 is essentially tied with that older Xeon. The i7-8809G’s nearest rival is the Intel Core i5-10400H, with a delta of 0.2%, so the i7 is essentially tied with a modern mainstream laptop chip. Both processors sit near the 48th percentile of all CPUs, with the i7 at 48 and the Xeon at 47.

Architecture Differences

The two chips come from different Intel design eras and target different markets. The i7-8809G is built on Kaby Lake architecture with the codename Kaby Lake G, using a 14 nm process node. It has 4 cores and 8 threads, with a base clock of 3.10 GHz and a boost clock of 4.20 GHz. Its cache layout is 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3. It supports DDR4 memory only, does not support ECC, and has no listed PCIe lanes. Critically, it integrates Radeon RX Vega M GH graphics, which is a major architectural feature—this is a mobile processor designed for compact systems that need discrete-level graphics performance without a separate GPU.

The Xeon D-1557 is a Broadwell architecture chip, specifically Broadwell-DE, also on a 14 nm node. It has 12 cores and 24 threads, with a base clock of 1.50 GHz and a boost clock of 2.10 GHz. Its cache is 64 KB of L1 per core, 256 KB of L2 per core, and 1.5 MB of L3 per core, which totals 18 MB of L3 across all 12 cores. It supports both DDR3 and DDR4 memory, has dual-channel memory bus, and supports ECC memory. It has 24 PCIe Gen 3 lanes (CPU only) and no integrated graphics. The die size is 246 mm² with 3,200 million transistors, whereas the i7-8809G has no listed die size or transistor count.

The core count difference is the most obvious architectural gap: 12 cores versus 4. The Xeon has three times the cores and three times the threads. But the clock speeds are reversed, with the i7 boosting to 4.20 GHz versus the Xeon’s 2.10 GHz. The Xeon’s L3 cache is larger in total (18 MB versus 8 MB), but it’s distributed per core rather than shared. The i7’s integrated Radeon RX Vega M GH graphics is a unique feature that the Xeon completely lacks, and the Xeon’s ECC support and dual-channel memory bus are server-grade features absent from the mobile i7. The market segments confirm the intended use: the i7 is marked as Mobile, the Xeon as Server/Workstation.

The Verdict

The data supports a clear conclusion: if you need consistent multi-threaded and single-threaded rendering performance in Cinebench-class workloads, the Intel Xeon D-1557 wins outright. It beats the i7-8809G by approximately 9% in every Cinebench R15, R20, and R23 test, both single and multi-core. Its 12 cores and 24 threads provide a structural advantage that the i7’s higher clock speeds cannot overcome. The Xeon also brings ECC memory support, dual-channel DDR3/DDR4, and 24 PCIe Gen 3 lanes, making it the appropriate choice for server or workstation environments where data integrity and expandability matter.

However, the i7-8809G is not a loser in this comparison. Its average benchmark score of 2307 is slightly higher than the Xeon’s 2282, driven by its Geekbench multicore score of 4590, which is not matched by the Xeon in this data set. The i7 also has integrated Radeon RX Vega M GH graphics, meaning it can handle graphics workloads without a discrete GPU, a capability the Xeon lacks entirely. For a compact mobile system that needs both CPU and GPU performance, the i7-8809G is the only viable option between these two. The Xeon’s launch MSRP of $694 also positions it as a higher-cost component, though this analysis does not factor pricing into performance verdicts.

The percentile rankings are nearly identical—48 for the i7, 47 for the Xeon—so neither chip is dramatically above or below the other in overall CPU hierarchy. The Xeon’s nearest rival is the Intel Xeon E5-2629 v3 with a 0% delta, indicating it is perfectly average among its peers. The i7’s nearest rival is the Intel Core i5-10400H with a 0.2% delta, also essentially average. The real differentiator is use case: the Xeon wins purely on CPU compute benchmarks, while the i7 wins on integration and versatility.

Where Each One Wins

The Xeon D-1557 wins in every Cinebench benchmark in this comparison, including single-core tests. That means for CPU rendering, video encoding, scientific computing, or any workload that scales with cores, the Xeon is the stronger choice. Its 12 cores and 24 threads provide a 50% core count advantage that translates to a steady 9% lead in all Cinebench iterations. The Xeon also wins for server deployments that require ECC memory, dual-channel memory support, and 24 PCIe Gen 3 lanes for expansion. Its 45-watt TDP is lower than the i7’s 65 watts, making it more power-efficient for always-on workloads.

The i7-8809G wins in scenarios where integrated graphics matter. With Radeon RX Vega M GH graphics built in, it can handle display output and some graphics acceleration without a separate GPU, which is impossible with the Xeon. The i7 also wins in Geekbench multicore, scoring 4590, though the Xeon has no Geekbench score to compare directly. Its higher boost clock of 4.20 GHz may translate to faster responsiveness in short, bursty workloads, even though the Cinebench single-core tests show the Xeon ahead. For a compact mobile system where space is limited and a discrete GPU is not an option, the i7-8809G is the only choice. The Xeon’s lack of integrated graphics means it requires a separate GPU, which is impractical for mobile or embedded designs. The i7 also has a higher average benchmark score (2307 versus 2282), so in aggregate, it performs comparably despite losing all head-to-head Cinebench tests.
