CPU Comparison

Intel Core i7-5775R vs Intel Core Ultra 5 225T

A side-by-side comparison of specs, performance and value. The Intel Core i7-5775R is a unique desktop processor based on the 14nm Broadwell architecture, distinguished by its use of BGA packaging and the inclusion of powerful Iris Pro Graphics. Designed primarily for All-in-One (AIO) systems and Intel NUCs, this chip is soldered directly to the motherboard. It features four cores and eight threads, operating at a base clock of 3.3 GHz and boosting up to 3.8 GHz. The standout feature is the integrated Intel Iris Pro Graphics 6200, which includes 128 MB of embedded L4 cache (eDRAM), drastically improving both graphical performance and CPU memory access speeds. With a 65-watt TDP, it balances performance and efficiency. The processor supports dual-channel DDR3 memory and provides 16 PCIe 3.0 lanes. While not intended for gaming with discrete GPUs, its integrated graphics were revolutionary for the time, allowing compact systems to handle moderate gaming and 4K media without a dedicated card.

Performance Compared

Productivity

Intel Core i7-5775R70

4 cores and high IPC handle office tasks effortlessly.

Intel Core Ultra 5 225TBest75

Handles office and development workloads well, but sustained multi-core tasks run slower due to power constraints.

Gaming

Intel Core i7-5775R50

Iris Pro 6200 can handle older or eSports titles at 720p/1080p Low.

Intel Core Ultra 5 225TBest70

Adequate for gaming when paired with a discrete GPU, but the 35W PL1 may cause lower 1% lows in CPU-bound scenarios compared to the standard 225.

Virtualization

Intel Core i7-5775R55

Capable of light VMs, but limited by 65W TDP.

Intel Core Ultra 5 225TBest65

10 threads are usable for light VM workloads, but power limits make it less ideal for running multiple VMs simultaneously.

Efficiency

Intel Core i7-5775RBest95

14nm process makes it incredibly power-efficient.

Intel Core Ultra 5 225T80

Excellent efficiency at base power, though the PL2 turbo window means actual power draw varies significantly under load.
