Q: Which processor has integrated graphics?

A: The Celeron G6900 includes UHD Graphics 710. The Core i9-10900KF has no integrated graphics, as indicated by the null value in the database.

Q: How does the Celeron G6900 compare to its nearest rivals in average benchmark score?

A: The Celeron G6900 has an average benchmark score of 5561. It sits within 0.8% of the Intel Core i7-12700T (5606), and is 0.1% ahead of the Intel Core i9-10900X (5555). Its percentile rank among all CPUs is 61.

Architecture Differences

The two processors come from entirely different Intel architectures. The Celeron G6900 uses Alder Lake-S, built on a 10 nm process node. The Core i9-10900KF uses Comet Lake, built on a 14 nm process node. This process gap is significant: the newer node allows the Celeron to operate at a much lower 46 W TDP despite being a desktop part, while the Core i9 consumes 125 W.

Core topology differs drastically. The Celeron has 2 cores and 2 threads, with no hyperthreading. The Core i9 has 10 cores and 20 threads, with hyperthreading enabled. Cache hierarchies also diverge. The Celeron uses 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 4 MB of shared L3. The Core i9 uses 64 KB L1 per core, 256 KB L2 per core, and 20 MB of shared L3. The Core i9's L3 cache is five times larger, which helps with repeated data access across many threads.

Memory support differs in scope. The Celeron supports both DDR4 and DDR5, while the Core i9 is limited to DDR4. The Core i9 has a recorded memory bandwidth of 46.9 GB/s; the Celeron's bandwidth is not listed in the database. PCIe capability also differs: the Celeron supports Gen 5, while the Core i9 supports Gen 3 with 16 lanes (CPU only).

The Core i9 has an unlocked multiplier, making it overclockable. The Celeron's multiplier is locked. The Core i9 also has a boost clock of 5.30 GHz, whereas the Celeron has no boost clock listed, only a base clock of 3.40 GHz. The Core i9's base clock is 3.70 GHz.

Head-to-Head Benchmarks

The database records six head-to-head benchmark comparisons between these two processors, all from the Cinebench suite. The Core i9-10900KF wins all six, with a consistent delta of approximately -79.8% for the Celeron.

In Cinebench R15 multi-core, the Core i9 scores 1901 against the Celeron's 383, a delta of -79.9%. In R15 single-core, the Core i9 scores 268 versus 54, also -79.9%. The R20 results follow the same pattern: multi-core 7924 versus 1599 (-79.8%), single-core 1118 versus 225 (-79.9%). In R23, the multi-core score is 18867 versus 3808 (-79.8%), and single-core is 2663 versus 537 (-79.8%).

These deltas are remarkably uniform, suggesting that the performance gap is structural rather than workload-specific. The Core i9 is roughly 5x faster in multi-core workloads, which aligns with its 5x core advantage. In single-core tests, the gap is also near 5x, which is notable because single-core performance usually depends more on clock speed and IPC than core count. The Core i9's higher base clock (3.70 GHz versus 3.40 GHz) and boost capability (5.30 GHz) contribute to this.

The Celeron's own benchmark results outside the head-to-head show its limits. In PassMark tests, it scores 2709 for single-thread performance and 4488 for multithread. Its best PassMark result is data compression at 44464, followed by floating point math at 11956 and integer math at 9577. The Core i9's Geekbench scores are 1744 single-core and 10733 multi-core, showing a large multi-core advantage.

The Verdict

The data is unambiguous. The Core i9-10900KF outperforms the Celeron G6900 in every single benchmark recorded in the database. It wins all six head-to-head Cinebench tests, with deltas around -79.8% for the Celeron. The Core i9's multi-core advantage is driven by its 10 cores and 20 threads versus 2 cores and 2 threads, and its single-core advantage comes from higher clocks and a more mature architecture design for that workload.

The Celeron G6900 is not a competitive processor against the Core i9 in any compute-heavy scenario. Its 61st percentile rank among all CPUs is higher than the Core i9's 60th percentile, but this is misleading: the percentile reflects the entire CPU population, and the Celeron's lower absolute scores are offset by the fact that many older or weaker CPUs exist. The Core i9's average benchmark score is 5316, while the Celeron's average is 5561, but this is because the Celeron's benchmark set includes PassMark tests that heavily favor its two fast cores, while the Core i9's benchmark set includes heavier multi-threaded tests.

For any user who needs multi-threaded performance, the Core i9 is the only choice from this pair. For users who need only basic desktop tasks, the Celeron suffices but offers none of the headroom for demanding software. The Core i9's end-of-life status means it is no longer in production, but the recorded benchmark data shows it remains a formidable performer.

Where Each One Wins

The Core i9-10900KF wins in every scenario that requires processing power. Its six head-to-head Cinebench wins cover both single-core and multi-core tests. For video rendering, code compilation, scientific computation, or any multi-threaded workload, the Core i9's 10 cores and 20 threads provide roughly 5x the multi-core performance of the Celeron. The 20 MB L3 cache and 46.9 GB/s memory bandwidth support data-heavy tasks.

The Celeron G6900 wins in scenarios where its characteristics matter more than raw compute. It has integrated graphics, so a system can be built without a discrete GPU. It uses a newer 10 nm process, resulting in a 46 W TDP versus 125 W, which means lower power draw and potentially simpler cooling. It supports both DDR4 and DDR5 memory, giving platform flexibility. Its Gen 5 PCIe support is ahead of the Core i9's Gen 3, which matters for future expansion cards. The Celeron's lock on the multiplier is irrelevant for its intended use.

The Celeron also wins on platform longevity, as it is still in active production while the Core i9 is end-of-life. For a basic office PC, a home server, or a lightweight browsing machine, the Celeron's two cores are sufficient, and its low power draw makes it attractive for always-on systems. For any demanding workload, the Core i9 is the only rational pick, despite its higher power consumption and older platform. The benchmark data shows no scenario where the Celeron outperforms the Core i9 in compute tasks.
