Intel Core i5-4590 vs Intel Core i9-10980XE Comparison

The Intel Core i9-10980XE and the Intel Core i5-4590 represent two distant eras of Intel desktop computing, and the benchmark data shows a complete sweep for the newer, high-end part. The i9-10980XE wins all eight head-to-head benchmark comparisons, with margins ranging from a modest 34.9% in Geekbench single-core to a dominant 501.6% in Cinebench R15 single-core. While the i5-4590 holds its own in the 63rd percentile of all CPUs, the i9-10980XE sits just above it in the 64th percentile, yet the raw performance gap between them is enormous, driven by a massive difference in core count, architecture, and memory bandwidth.

FAQ

Q: What is the most significant performance gap between the two processors?

A: The largest single benchmark delta is in Cinebench R15 single-core, where the Intel Core i9-10980XE scores 385 versus the Intel Core i5-4590's 64, a 501.6% difference. This indicates that even in lightly-threaded tasks, the newer architecture and higher boost clock of the i9 provide a substantial advantage.

Q: How do the two CPUs compare in multi-threaded workloads?

A: The i9-10980XE dominates multi-threaded tests. In Cinebench R23 multi-core, it scores 27130 compared to the i5-4590's 4573, a 493.3% delta. Similarly, in Geekbench multi-core, the i9 scores 14742 versus 3156 for the i5, a 367.1% advantage, reflecting the i9's 18 cores and 36 threads versus the i5's 4 cores and 4 threads.

Q: Are there any benchmarks where the i5-4590 comes close to the i9-10980XE?

A: The closest result is in Geekbench single-core, where the i9-10980XE scores 1453 and the i5-4590 scores 1077, a 34.9% delta. While this is the smallest relative gap, the i9 still wins decisively, and no benchmark in the data shows the i5 taking a lead.

Q: What are the architectural generations of these two CPUs?

A: The Intel Core i9-10980XE is based on the Cascade Lake architecture, built on a 14 nm process node, and belongs to the Core 10th Gen series. The Intel Core i5-4590 uses the older Haswell architecture, built on a 22 nm process node, and is part of the Core i5 (Haswell) generation.

Q: How does the memory support differ between the two?

A: The i9-10980XE supports DDR4 memory with a quad-channel bus and a peak memory bandwidth of 93.9 GB/s. The i5-4590 supports older DDR3 memory with a dual-channel bus, and no memory bandwidth figure is listed for it in the data.

Q: Which CPU has a higher boost clock speed?

A: The Intel Core i9-10980XE has a boost clock of 4.80 GHz, which is higher than the Intel Core i5-4590's boost clock of 3.70 GHz. This contributes to the i9's lead in single-threaded tests, despite the i5 having a slightly higher base clock of 3.30 GHz versus the i9's 3.00 GHz.

Where Each One Wins

Based strictly on the head-to-head benchmark data, the Intel Core i9-10980XE wins in every single test category. The i5-4590 does not win a single benchmark in the comparison, making the use-case split very clear. The i9-10980XE is the only choice for any workload that benefits from high multi-threaded performance, such as rendering, video encoding, or scientific computing, where its 18-core, 36-thread configuration provides massive parallel throughput. Its lead in Cinebench R23 multi-core, scoring 27130 versus 4573, illustrates this advantage.

The i9-10980XE also wins in single-threaded performance, which is critical for everyday responsiveness and lightly-threaded applications. Its Geekbench single-core score of 1453 versus the i5-4590's 1077 shows a 34.9% advantage, meaning even in tasks that do not utilize all cores, the newer processor is faster. The i5-4590, with its 4 cores and 4 threads, is relegated to a legacy role, suitable only for basic computing tasks where the absolute performance ceiling is not a limiting factor. The data does not support any scenario where the i5-4590 is the superior processor.

Architecture Differences

The architectural gap between these two CPUs is generational. The i9-10980XE uses the Cascade Lake architecture, which is the high-end desktop variant of Intel's 14 nm process node, while the i5-4590 uses the Haswell architecture on Intel's older 22 nm process node. This process shrink allows the i9 to pack more transistors and features into a similar power envelope, despite having a higher TDP of 165 watts versus the i5's 84 watts.

The core and thread counts are the most obvious architectural divergence. The i9-10980XE features 18 physical cores and 36 threads, enabling simultaneous multithreading, whereas the i5-4590 is a quad-core, quad-thread part with no hyper-threading. The cache hierarchy also differs significantly: the i9 has 64 KB of L1 and 1 MB of L2 cache per core, plus a shared 24.75 MB L3 cache. The i5 has 64 KB of L1 and 256 KB of L2 per core, with a much smaller 6 MB shared L3 cache.

Memory architecture is another key differentiator. The i9-10980XE supports quad-channel DDR4 memory with a theoretical bandwidth of 93.9 GB/s, while the i5-4590 uses dual-channel DDR3. This memory bandwidth advantage is crucial for feeding the i9's 18 cores in memory-intensive workloads. The i9 also features a PCIe Gen 3 interface with 48 lanes from the CPU, whereas the i5 has a standard PCIe Gen 3 implementation without a specified lane count. The i9 has an unlocked multiplier for overclocking, while the i5 is locked, and the i5 includes integrated graphics (Intel HD 4600) whereas the i9 does not.

Specification Differences

The two processors differ across nearly every core specification. The i9-10980XE has 18 cores and 36 threads, while the i5-4590 has 4 cores and 4 threads. The i9's base clock is 3.00 GHz with a boost clock of 4.80 GHz, compared to the i5's base of 3.30 GHz and boost of 3.70 GHz. The i9 has a TDP of 165 watts, while the i5 consumes 84 watts.

The i9 uses the Intel Socket 2066 platform, whereas the i5 uses the older Intel Socket 1150. The process node is 14 nm for the i9 and 22 nm for the i5. The i9's cache configuration includes 1 MB of L2 per core and 24.75 MB of shared L3, while the i5 has 256 KB of L2 per core and 6 MB of shared L3. The i9 supports DDR4 memory with a quad-channel bus and 93.9 GB/s bandwidth; the i5 supports DDR3 with a dual-channel bus and no bandwidth specification. The i9 is an unlocked part, while the i5 is locked, and the i5 features integrated Intel HD 4600 graphics that the i9 lacks. The i9 has a launch MSRP of $1076, while no launch MSRP is listed for the i5.

Head-to-Head Benchmarks

The benchmark results are uniformly one-sided, but the magnitude of the wins varies. The largest relative margin is in Cinebench R15 single-core, where the i9-10980XE scores 385 against the i5-4590's 64, a 501.6% delta. This is a massive generational leap in per-core performance, reflecting both the higher boost clock and architectural improvements. The multi-core versions of the same test show similar dominance: Cinebench R15 multi-core sees the i9 at 2734 versus 460, a 494.3% delta, and Cinebench R20 multi-core shows 11394 versus 1920, a 493.4% delta.

In Cinebench R23, the i9-10980XE scores 27130 in multi-core and 3830 in single-core, versus the i5-4590's 4573 and 645, respectively, yielding deltas of 493.3% and 493.8%. These numbers confirm that the i9's advantage scales consistently across different rendering workloads. The Geekbench results show a slightly different pattern: multi-core gives the i9 a 367.1% lead (14742 versus 3156), while single-core narrows to a 34.9% delta (1453 versus 1077). The single-core Geekbench gap is the smallest in the entire dataset, but it still represents a clear win for the i9. Across all eight head-to-head benchmarks, the i9-10980XE records 8 wins and 0 losses.

The Verdict

The data is unambiguous: the Intel Core i9-10980XE is the superior processor in every measured category. Anyone requiring maximum multi-threaded performance for content creation, 3D rendering, or heavy multitasking should choose the i9-10980XE, based on its 493.3% lead in Cinebench R23 multi-core and its 18-core, 36-thread configuration. The processor's quad-channel DDR4 memory and 93.9 GB/s of bandwidth further cement its position for data-intensive workloads.

The Intel Core i5-4590, despite being in the 63rd percentile of all CPUs, is outclassed by a significant margin. Its 4 cores and 4 threads are insufficient for modern high-end workloads, and its performance is below the i9 in all benchmarks, including single-threaded tests where the i9 leads by 34.9% in Geekbench. The i5-4590 should only be considered for legacy systems or basic tasks where the higher power consumption and platform cost of the i9 are not justified. The benchmark data does not offer a single scenario where the i5-4590 emerges as the recommended pick over the i9-10980XE.
