Intel Core i5-4690T vs Intel Xeon D-1518 Comparison

The Intel Xeon D-1518 and Intel Core i5-4690T are both 4-core Intel processors, but they target entirely different worlds: one is a low-power server chip, the other a desktop part. Benchmark results show they are remarkably close in raw compute performance, yet the data reveals distinct strengths. The Xeon D-1518 brings server features like ECC memory support and a different socket, while the i5-4690T counters with a higher clock speed and integrated graphics. This analysis breaks down the numbers to help you decide which fits your specific needs.

Head-to-Head Benchmarks

The benchmark data paints a picture of near-total parity, with the Core i5-4690T taking a narrow win in every single test. In Cinebench R15, the multicore score shows the i5-4690T at 393 against the Xeon D-1518’s 390, a delta of -0.8% in favor of the desktop chip. The single-core R15 test is slightly more lopsided, with the i5-4690T scoring 55 versus 54, a -1.8% difference. These are negligible margins, but they are consistent.

Moving to Cinebench R20, the pattern holds. The multicore result is 1640 for the i5-4690T and 1628 for the Xeon D-1518, a -0.7% delta. In single-core R20, the i5-4690T scores 231 against 229, a -0.9% gap. The most recent Cinebench R23 test reinforces the trend: the i5-4690T leads with 3905 in multicore versus 3877, and 551 in single-core versus 547, both at -0.7%.

The data shows the i5-4690T wins all six head-to-head comparisons. However, the largest victory margin is a mere -1.8%, and most are under -1%. This suggests that in everyday workloads, the two processors would feel nearly identical. The Xeon D-1518’s 8 threads help it stay competitive with the i5-4690T’s higher base clock, but they are not enough to overcome the desktop chip’s advantage. The average benchmark score for the Xeon D-1518 is 1121, while the i5-4690T sits slightly higher at 1129, a difference of less than 1%. Both processors land in the 32nd percentile of all CPUs, indicating they are entry-level performers by modern standards.

Architecture Differences

The architectural divide is stark. The Xeon D-1518 is built on Intel’s Broadwell architecture using a 14 nm process node, while the Core i5-4690T uses the older Haswell architecture on a 22 nm node. This process advantage is significant, as it allows the Xeon D-1518 to achieve a lower 35W TDP despite running more threads. The i5-4690T, by contrast, has a 45W TDP. The Xeon D-1518 packs 3,200 million transistors on a 246 mm² die, compared to 1,400 million transistors on a 177 mm² die for the i5-4690T.

Core counts are identical at 4, but threading differs. The Xeon D-1518 supports 8 threads via Hyper-Threading, while the i5-4690T is limited to 4 threads. This is a crucial differentiator for multi-threaded server workloads. The Xeon D-1518’s base clock is 2.20 GHz, whereas the i5-4690T runs at 2.50 GHz base and can boost to 3.50 GHz. The Xeon D-1518 has no boost clock listed. Cache layouts also diverge: the Xeon D-1518 has 1.5 MB of L3 cache per core, while the i5-4690T has 6 MB of shared L3 cache.

Memory support is a major split. The Xeon D-1518 supports both DDR3 and DDR4 memory, while the i5-4690T only supports DDR3. Crucially, the Xeon D-1518 supports ECC memory, which is a non-negotiable feature for many server and workstation environments. The i5-4690T does not support ECC. The i5-4690T does have integrated Intel HD 4600 graphics, while the Xeon D-1518 has no integrated graphics at all. PCIe lanes also differ: the Xeon D-1518 offers Gen 3 with 24 lanes, while the i5-4690T offers Gen 3 with 16 lanes. The sockets are incompatible: the Xeon D-1518 uses Intel BGA 1667 (soldered), while the i5-4690T uses the LGA 1150 socket.

Where Each One Wins

The Core i5-4690T wins on raw performance in every benchmark category, but the margins are so thin that they only matter in specific, isolated scenarios. For single-threaded tasks, the i5-4690T’s 3.50 GHz boost clock gives it a clear edge, which is reflected in the -1.8% delta in Cinebench R15 single-core. This makes the i5-4690T the better choice for older games or lightly-threaded applications that rely on a single core’s speed. The i5-4690T also benefits from integrated graphics, so a system built around it can operate without a discrete GPU for basic display output.

The Xeon D-1518 wins in scenarios where its server features matter more than raw clock speed. Its 8 threads provide a theoretical advantage in heavily multi-threaded workloads, though the benchmark data shows this does not translate to a victory in Cinebench’s multicore tests. The real wins for the Xeon D-1518 are its ECC memory support, which is critical for data integrity in servers, and its lower 35W TDP, which makes it suitable for dense, power-constrained environments. The 24 PCIe lanes also offer more expansion headroom for server applications like NVMe storage or networking cards. The Xeon D-1518 is produced for the server/workstation segment and is marked as Active in production, whereas the i5-4690T has no production status listed.

FAQ

Q: Which processor is faster in multi-core workloads?

The Verdict

The data points to a clear but nuanced conclusion. If you are building a desktop system where single-thread performance, integrated graphics, and a higher boost clock are priorities, the Core i5-4690T is the better choice. It wins every benchmark, even if only by a sliver, and its 3.50 GHz boost clock gives it a tangible edge in everyday applications that do not fully utilize multiple threads. The i5-4690T’s 6 MB of shared L3 cache also provides a simpler, more unified cache structure for desktop workloads.

However, if your use case is a server or workstation where data integrity and expansion are critical, the Xeon D-1518 is the only viable option. Its ECC memory support is non-negotiable for error-free operation in long-running, memory-sensitive tasks. The 24 PCIe lanes offer more bandwidth for high-speed peripherals, and the lower 35W TDP allows for more efficient cooling in dense chassis. The Xeon D-1518’s support for both DDR3 and DDR4 memory provides flexibility in system design. The 8 threads are a theoretical advantage, but the benchmark data shows they do not translate to a performance win in Cinebench. For a pure performance-per-dollar desktop build, the i5-4690T wins. For a reliable server node, the Xeon D-1518 is the only choice based on features alone.
