AMD Ryzen 9 4900HS vs Intel Xeon E5-1650 v3 Comparison

The AMD Ryzen 9 4900HS and Intel Xeon E5-1650 v3 represent two very different eras and purposes in CPU design, with a 2014 workstation part facing a 2020 mobile flagship. The benchmark data shows a clear generational gap, but the Xeon still holds distinct advantages in platform capabilities, making the choice highly dependent on the specific workload and system requirements.

Head-to-Head Benchmarks

The data shows a decisive victory for the AMD Ryzen 9 4900HS in the two benchmarks where both processors were tested. In Cinebench R15 multi-core, the Ryzen 9 4900HS scores 1863 against the Xeon E5-1650 v3's 887, resulting in a 110% advantage. This is a massive delta, meaning the AMD chip delivers more than double the multi-threaded rendering performance of the Intel part. The advantage is not just about raw core count, as the Ryzen does have 8 cores versus 6, but also reflects the efficiency of the Zen 2 architecture.

In the single-core Cinebench R15 test, the results are similarly one-sided. The Ryzen 9 4900HS scores 193, while the Xeon E5-1650 v3 scores 125, giving AMD a 54.4% lead. This is a significant margin, showing that the Ryzen is substantially faster in lightly-threaded tasks like older games or general desktop responsiveness. The Xeon's higher base clock of 3.50 GHz compared to the Ryzen's 3.00 GHz does not help it overcome the architectural and IPC improvements of the newer Zen 2 design.

While the Xeon was not tested in the same additional benchmarks as the Ryzen, its available scores from other tests (Cinebench R20 multi-core 3696, R23 multi-core 8800) are not directly comparable to the Ryzen's other numbers (Geekbench multi-core 6926, single-core 1311). The only direct head-to-head comparisons are the two Cinebench R15 tests, and the AMD processor wins both with overwhelming margins. The overall win count is 2 for the Ryzen 9 4900HS and 0 for the Xeon E5-1650 v3, which accurately reflects the performance hierarchy in the shared test suite.

Architecture Differences

The fundamental gap between these two processors lies in their architectural generation and design philosophy. The AMD Ryzen 9 4900HS is built on the Zen 2 architecture, codenamed Renoir, using a 7 nm process at TSMC. It is a mobile-focused part with a 35W TDP, designed for high performance per watt. The Intel Xeon E5-1650 v3, in contrast, is based on the Haswell architecture, codenamed Haswell-EP, manufactured on a 22 nm process at Intel. It is a server/workstation chip with a 140W TDP, prioritizing raw throughput over efficiency.

The transistor count illustrates the complexity difference: the Ryzen packs 9,800 million transistors into a die size of 156 mm², while the Xeon has only 2,600 million transistors on a much larger 356 mm² die. This is a direct result of the process node advantage, allowing AMD to pack more functionality into a smaller, more power-efficient package. The Xeon's larger die and older process contribute to its significantly higher TDP.

Cache layouts also differ. Both have 64 KB of L1 cache per core, but the Ryzen has 512 KB of L2 per core, while the Xeon has 256 KB per core. For L3 cache, the Ryzen has 8 MB shared, while the Xeon has a larger 15 MB shared pool. The Xeon's larger L3 cache is a holdover from its server heritage, but it does not compensate for the Ryzen's superior core efficiency and clock speeds. The Ryzen also features integrated Radeon Graphics 512SP, while the Xeon has no integrated graphics, requiring a discrete GPU for any display output.

FAQ

Q: Which processor has more cores and threads?

A: The AMD Ryzen 9 4900HS has 8 cores and 16 threads, while the Intel Xeon E5-1650 v3 has 6 cores and 12 threads. The AMD part offers two additional cores and four additional threads.

Q: Does the Intel Xeon support ECC memory?

A: Yes, the Intel Xeon E5-1650 v3 supports ECC memory. The AMD Ryzen 9 4900HS does not have ECC memory support, making the Xeon a better fit for error-sensitive workstation tasks.

Q: What is the difference in memory bandwidth?

A: The Intel Xeon E5-1650 v3 has a quad-channel memory bus with a bandwidth of 68.3 GB/s, while the AMD Ryzen 9 4900HS has a dual-channel bus with a bandwidth of 51.2 GB/s. The Xeon offers higher theoretical memory throughput.

Q: Which processor has a higher boost clock?

A: The AMD Ryzen 9 4900HS has a boost clock of 4.30 GHz, which is significantly higher than the Intel Xeon E5-1650 v3's boost clock of 3.80 GHz. The Ryzen also has a lower base clock of 3.00 GHz versus the Xeon's 3.50 GHz.

Q: What are the socket types for each processor?

A: The AMD Ryzen 9 4900HS uses the AMD Socket FP6 (a mobile socket), while the Intel Xeon E5-1650 v3 uses the Intel Socket 2011-3 (a desktop/workstation socket). This means they are not interchangeable on any platform.

Q: Is the Intel Xeon still in production?

A: No, the Intel Xeon E5-1650 v3 is marked as End-of-life, while the AMD Ryzen 9 4900HS is listed as Active in production.

Specification Differences

The specification sheets show stark contrasts in every major category. The AMD Ryzen 9 4900HS has 8 cores and 16 threads, compared to the Intel Xeon E5-1650 v3's 6 cores and 12 threads. The Ryzen's base clock is 3.00 GHz, but its boost clock reaches 4.30 GHz, whereas the Xeon has a higher base clock of 3.50 GHz but a lower boost of 3.80 GHz. The TDP is a major separator: the Ryzen is rated at 35W, while the Xeon is rated at 140W, a four-fold difference.

The process nodes are generations apart: 7 nm for the Ryzen versus 22 nm for the Xeon. The Ryzen has a larger L2 cache per core (512 KB vs 256 KB), but the Xeon has a larger shared L3 cache (15 MB vs 8 MB). The Ryzen features an unlocked multiplier? No, it is locked, while the Xeon has an unlocked multiplier. The Ryzen supports DDR4 memory over a dual-channel bus, while the Xeon supports DDR4 over a quad-channel bus. The Ryzen has integrated Radeon Graphics, while the Xeon has none. The market segments are also distinct: Mobile for the AMD chip and Server/Workstation for the Intel chip. Finally, the sockets are completely different: AMD Socket FP6 versus Intel Socket 2011-3.

Where Each One Wins

The AMD Ryzen 9 4900HS wins in every directly comparable performance benchmark, making it the clear choice for tasks that rely on per-core speed and multi-threaded rendering. Its 110% lead in Cinebench R15 multi-core and 54.4% lead in single-core make it the superior processor for general productivity, software compilation, and content creation such as video editing or 3D rendering. The massive efficiency advantage of a 35W TDP also makes it ideal for compact systems, laptops, and any build where heat generation and power draw are primary concerns. Its integrated Radeon Graphics provide a basic display output capability, which is a bonus for simple systems without a discrete GPU.

The Intel Xeon E5-1650 v3, despite its performance deficit, has clear wins in platform-specific features. Its support for ECC memory is a critical feature for data integrity in servers and professional workstations. The quad-channel memory bus with 68.3 GB/s bandwidth offers higher theoretical throughput, which can benefit memory-bandwidth-sensitive workloads like large-scale data analysis or virtualization. Its unlocked multiplier allows for overclocking, and its 40 PCIe Gen 3 lanes (CPU only) provide more expansion capability for multiple GPUs or high-speed storage controllers. The Xeon also targets a different market segment (Server/Workstation) and uses a different socket (Intel Socket 2011-3), meaning it can be installed in existing workstation motherboards that support that platform.

The Verdict

The data is unambiguous: the AMD Ryzen 9 4900HS is the faster processor in every head-to-head benchmark, and it does so while consuming a fraction of the power. Any user prioritizing raw CPU performance, whether single-core or multi-core, should choose the AMD part based on the benchmark results. Its modern architecture and active production status also suggest it will remain relevant for a longer period.

The Intel Xeon E5-1650 v3, however, is not without merit. It is the correct choice for users who require the specific platform features that the Ryzen lacks: ECC memory support, quad-channel memory bandwidth, and a high lane-count PCIe Gen 3 setup for expansion. If you are building a new system from scratch and performance is the goal, the Ryzen 9 4900HS is the logical pick. If you have an existing LGA 2011-3 motherboard or need the data integrity and memory throughput of a workstation platform, the Xeon E5-1650 v3 remains a viable, though slower, option. The final decision rests on whether you need the Ryzen's superior speed and efficiency or the Xeon's specialized platform capabilities.
