Intel Core i5-5575R

The Intel Core i5-5575R is a 4-core, 4-thread desktop processor built on Intel’s 14nm Broadwell architecture. It runs at a 2.80 GHz base clock and 3.30 GHz boost, with a 65W TDP. Its average benchmark score across the suite is 1477, placing it in the 39th percentile of all CPUs. That puts it in a tight cluster with several older mid-range parts, as shown by its nearest rivals. Its launch MSRP was $265.

How It Compares

The i5-5575R trails the Intel Core i5-7500T by just 0.3% in average benchmark score (1477 vs 1481). That is a rounding error in practice; the two chips are effectively interchangeable for everyday workloads. The 7500T is a lower-clocked part from a later generation, yet the performance difference is negligible, meaning the 5575R holds its own against a newer mainstream chip.

Against the Core i5-6600, the 5575R is 0.7% slower (1488 average). The i5-6600 is a familiar desktop part from the Skylake generation, and the 5575R sits within the same performance band. The gap is so small that any real-world difference would be invisible outside synthetic benchmarks.

The 5575R edges out the Core i3-7350K by 0.9% (1477 vs 1464). The i3-7350K is a dual-core with an unlocked multiplier and a higher boost clock, but the 5575R’s four physical cores give it a slight advantage in multi-threaded tasks. This is a case where core count outweighs clock speed.

Finally, the 5575R is 1% slower than the AMD Opteron 6344 (1492 average). That server-class chip has many more cores, but its older architecture and lower per-core efficiency keep it in the same overall performance envelope. The delta is within 1%, so the 5575R is competitive even against a heavily multi-core server part.

Single-Thread vs Multi-Thread Behavior

The benchmark split reveals a clear personality. In Cinebench R23, the 5575R scores 609 in single-core and 4320 in multi-core. That is a ratio of about 7.1:1, which is unusually high for a 4-core processor. Normally, a 4-core chip with good scaling would show a ratio near 4:1. The extreme ratio here indicates that the single-core performance is very weak relative to the multi-core result. The multi-core score of 4320 is respectable for a 4-thread part, but the single-core score of 609 is low in absolute terms.

Geekbench tells a similar story but with a more typical ratio: single-core 1072, multi-core 3247, a 3.0:1 spread. That is closer to what you’d expect from four cores. The discrepancy between the two tests suggests that the R23 single-core workload is particularly sensitive to the chip’s frequency behavior, while the Geekbench test is more forgiving.

For real workloads, this means the 5575R will feel sluggish in applications that depend on one or two fast cores—such as older games, some office macros, or lightly threaded productivity tools. On the other hand, fully threaded workloads like video encoding, 3D rendering, or batch image processing will use all four cores effectively. The 4320 R23 multi-core score is strong enough for occasional content creation, but the 609 single-core score will be a bottleneck in any task that cannot parallelize.

Power and Thermals

The 65W TDP places the 5575R in the mainstream efficiency class. Built on a 14nm process with a die size of 182 mm², the chip runs cool enough for a standard air cooler. No exotic cooling is required; a typical tower cooler or even a compact low-profile unit will handle it. Because the processor is soldered to the motherboard (BGA 1364), the cooling solution is part of the board design, so you won’t be swapping coolers. The 65W rating means the board’s stock cooler or any reasonable aftermarket option will keep temperatures in check.

The 14nm process is a key factor here. It allows the 5575R to maintain its modest TDP while delivering the benchmark scores seen above. The 29.9 GB/s memory bandwidth is also in line with a dual-channel DDR3 setup, which is sufficient for the CPU’s performance level.

FAQ

Q: What socket does the i5-5575R use?

A: It uses Intel BGA 1364, which is a soldered, non-upgradeable socket. The CPU is permanently attached to the motherboard.

Q: Does it support ECC memory?

A: No, ECC memory is not supported. The memory controller is limited to non-ECC DDR3.

Q: What integrated graphics does it have?

A: It includes Iris Pro Graphics 6200, a capable integrated GPU for basic display output and light media acceleration.

Q: Is the multiplier unlocked?

A: No, the multiplier is locked. Overclocking is not possible, and the boost clock of 3.30 GHz is the maximum achievable.

Q: What memory type does it support?

A: It supports dual-channel DDR3 memory with a bandwidth of 29.9 GB/s.

Q: When was it released?

A: It was released on May 14, 2015.

Who Should Consider It

The 5575R is best suited for general office tasks, spreadsheet work, web browsing, and light multitasking. Its single-core score of 609 in Cinebench R23 suggests it will feel underpowered in CPU-bound games that rely on a single fast core. Modern titles, especially those with high physics or AI demands, will likely see lower frame rates compared to chips with stronger per-core performance.

For multi-threaded productivity, the 4320 R23 multi-core score is acceptable for occasional video editing or photo rendering. The four threads will handle short bursts of heavy work, but sustained rendering will be bottlenecked by the lack of additional threads. If you regularly run long encodes or complex simulations, a newer part with more cores would be a better fit.

On the other hand, if you already have a compatible BGA 1364 board and need a low-power, soldered CPU for a compact or embedded-style desktop, the 5575R is a viable choice. Its 65W TDP and integrated Iris Pro graphics keep the system simple, and its performance is within 1% of several well-known older desktop chips. For basic office machines or HTPCs, it gets the job done without demanding high-end cooling or a large power supply.

Platform and Compatibility

The i5-5575R uses the Intel BGA 1364 socket, meaning it is soldered directly to the motherboard. There is no upgrade path; you cannot swap the CPU later. This is a fixed-platform design, so the entire board must be replaced if you need more performance. The chip supports dual-channel DDR3 memory with a bandwidth of 29.9 GB/s, and it does not support ECC memory.

For expansion, the CPU provides 16 PCIe Gen 3 lanes. These are dedicated to the CPU, so a single high-end graphics card or multiple lower-bandwidth devices can be accommodated. The integrated Iris Pro Graphics 6200 handles display output, so a discrete GPU is optional for basic use. The platform lacks any overclocking features, and the locked multiplier reinforces its position as a mainstream, non-enthusiast part.

Given its release date of May 14, 2015, and the soldered design, the 5575R is now a legacy component. It is best considered for systems that already have a compatible board or for niche applications where a low-power, fixed CPU is acceptable. The 39th percentile ranking and average score of 1477 place it below the current mainstream, but its performance cluster with the i5-7500T, i5-6600, and i3-7350K shows that it remains competitive with a generation of CPUs that are still in use today.
