AMD Ryzen Embedded V3C18I vs Intel Core i9-9900T Comparison

Head-to-Head Benchmarks

The benchmark database records a clean sweep for the AMD Ryzen Embedded V3C18I across all six Cinebench comparisons. The AMD part wins every multicore and single-core test, with deltas that remain remarkably consistent. In Cinebench R15 multicore, the AMD chip scores 1187 against 1117 for the Intel Core i9-9900T, a 6.3% advantage. The single-core R15 result is 167 versus 157, a 6.4% edge. The pattern holds through R20, where the AMD processor posts 4946 multicore and 698 single-core, while the Intel chip manages 4658 and 657 respectively, both results showing a 6.2% gap. The latest R23 test repeats the same story: the V3C18I scores 11777 multicore and 1662 single-core, versus 11091 and 1565 for the i9-9900T, again a 6.2% difference. The AMD part wins all six head-to-head tests, and the Intel part records zero wins.

What stands out is not just the direction of the results but the uniformity of the margin. A 6.2% to 6.4% spread across every workload suggests a consistent architectural advantage rather than a workload-specific quirk. The recorded data shows the AMD part is faster in both lightly threaded tasks, where single-core performance dominates, and fully threaded rendering, where all 16 threads are active. The Intel part cannot close the gap in any scenario within the Cinebench suite.

Looking at the broader database context, the AMD Ryzen Embedded V3C18I sits at the 54th percentile among all CPUs, with an average benchmark score of 3406. Its nearest rivals include the Intel Xeon E-2236 at 3410 (a 0.1% deficit) and the Intel Xeon E-2146G at the same score, while the AMD Ryzen 5 PRO 7530U trails at 3394 (0.4% behind). The Intel Core i9-9900T ranks slightly higher at the 55th percentile, with an average score of 3499. Its nearest comparison points are the Intel Xeon E-2176G at 3502 (0.1% ahead), the Intel Xeon E5-1680 v4 at 3494 (0.2% behind), and the Intel Xeon D-1732TE at 3486 (0.4% behind). Despite the i9-9900T holding a slightly higher percentile, the direct head-to-head Cinebench results favor the AMD part in every measured test.

The database also includes Geekbench results for the Intel part only: 7298 multicore and 1452 single-core. No corresponding Geekbench score exists for the AMD chip in the recorded data, so a direct comparison on that test is not possible. However, the Cinebench suite provides a consistent and complete picture for both processors.

The Verdict

The data points to a straightforward choice for most workloads. The AMD Ryzen Embedded V3C18I wins every Cinebench test in the database, with margins between 6.2% and 6.4%. Anyone prioritizing raw rendering performance in applications that use Cinebench-style workloads should select the AMD part. It also does so while carrying a 15 W TDP, whereas the Intel Core i9-9900T carries a 35 W TDP. That is a meaningful efficiency gap, and the AMD chip uses less power while producing higher scores.

The Intel Core i9-9900T does have one clear advantage: it includes integrated graphics in the form of UHD Graphics 630. The AMD part lists no integrated graphics, so a system built around it requires a discrete GPU. For applications that rely on integrated display output or quick troubleshooting without a separate card, the Intel part is the practical option. The Intel chip also supports DDR4 memory, which may be simpler or cheaper to source in existing systems, while the AMD part uses DDR5.

The production status differs as well. The AMD Ryzen Embedded V3C18I is marked Active, while the Intel Core i9-9900T is End-of-life. New designs should favor the active part for availability and long-term support. The Intel part has a recorded launch MSRP of $423, but the database does not list a launch price for the AMD part, so no direct cost comparison is possible from the recorded facts.

The recommendation is clear: pick the AMD Ryzen Embedded V3C18I for compute-heavy tasks where Cinebench performance and lower power draw matter most. Pick the Intel Core i9-9900T only if you need integrated graphics or must stay on DDR4 memory infrastructure.

Specification Differences

The two processors differ on several core specifications. The AMD Ryzen Embedded V3C18I has a base clock of 1900 MHz and a boost clock of 3.80 GHz. The Intel Core i9-9900T runs at a 2.10 GHz base clock and boosts to 4.40 GHz. Despite the Intel part's higher clock speeds, the AMD chip produces higher benchmark scores, indicating that its architecture delivers more work per clock cycle.

The TDP difference is substantial: the AMD part is rated at 15 W, while the Intel part is rated at 35 W. That is a 20 W gap and directly reflects the efficiency of the two designs. The AMD chip achieves better performance while drawing less than half the power envelope.

The sockets are not compatible. The AMD part uses AMD Socket FP7, while the Intel part uses Intel Socket 1151. Any system build must match the motherboard accordingly. The process nodes also differ: the AMD chip is built on a 6 nm process at TSMC, while the Intel chip uses a 14 nm process at Intel. The Intel part has a recorded die size of 180.3 mm², while no die size is recorded for the AMD chip.

Memory support diverges completely. The AMD part uses DDR5 with dual-channel configuration and 76.8 GB/s bandwidth, and it supports ECC. The Intel part uses DDR4 with dual-channel configuration and 42.7 GB/s bandwidth, with no ECC support. PCIe connectivity differs as well: the AMD chip provides Gen 4 with 20 lanes, while the Intel chip provides Gen 3 with 16 lanes.

The Intel part includes integrated graphics (UHD Graphics 630); the AMD part does not list any. The AMD part is marked as Active production status, while the Intel part is End-of-life. The Intel part has a launch MSRP of $423, while no launch MSRP is recorded for the AMD part. The release dates also differ: the AMD part entered the database in September 2022, while the Intel part was released in April 2019.

Architecture Differences

The architectural gap explains the benchmark results. The AMD Ryzen Embedded V3C18I uses the Zen 3+ architecture, codenamed Rembrandt, built on a 6 nm process at TSMC. The Intel Core i9-9900T uses the Coffee Lake architecture, specifically Coffee Lake-R, built on a 14 nm process at Intel. The node difference is substantial: 6 nm versus 14 nm, which directly impacts transistor density and power efficiency.

Both processors have 8 cores and 16 threads, so the thread count is identical. The cache configurations differ in the L2 cache: the AMD part carries 512 KB per core, while the Intel part carries 256 KB per core. L1 cache is the same at 64 KB per core, and L3 cache is also the same at 16 MB shared. The larger L2 cache on the AMD part likely contributes to its performance edge.

The AMD part is based on the Ryzen Embedded generation (Zen 3+ Rembrandt), and its part number is 100-000000559. The Intel part is from the Core i9 generation (Coffee Lake Refresh), with part number SRG1B. Neither processor has an unlocked multiplier, so overclocking is not supported on either chip.

The memory controllers reflect the respective platforms: the AMD chip supports DDR5 with ECC, which is typical for embedded and workstation-oriented parts, while the Intel chip supports DDR4 without ECC. PCIe generation also differs, with the AMD part offering Gen 4 lanes versus Gen 3 on the Intel part. The AMD chip's 20 lanes versus 16 lanes on the Intel part gives it additional connectivity headroom.

Where Each One Wins

The AMD Ryzen Embedded V3C18I wins in every recorded Cinebench benchmark, both multicore and single-core. That makes it the clear choice for rendering, video encoding, 3D modeling, and any workload that scales with thread count or benefits from strong single-thread performance. The 15 W TDP also makes it suitable for compact, power-constrained systems such as embedded appliances, fanless builds, or always-on servers. Its DDR5 support and ECC capability further position it for reliability-focused applications.

The Intel Core i9-9900T wins in scenarios that require integrated graphics. With UHD Graphics 630 on the die, it can drive displays without a separate GPU, which is useful for office desktops, media centers, or troubleshooting stations. Its DDR4 support may also be an advantage in existing systems where DDR4 memory is already installed and DDR5 would require a platform change. The higher base clock of 2.10 GHz and boost clock of 4.40 GHz suggest it may feel snappier in short, latency-sensitive tasks, though the benchmark data does not confirm any such advantage in the recorded tests.

For new builds where performance and efficiency are priorities, the AMD part is the stronger pick. For legacy systems or applications that need integrated graphics, the Intel part remains viable. The database shows no benchmark where the Intel part outperforms the AMD chip, so the decision rests on platform compatibility and feature requirements rather than measured compute performance.
