The Intel Core i5-4670T is a quad-core desktop processor released in June 2013 under the Haswell architecture. Built on a 22 nm process, it distinguishes itself by offering four physical cores without Hyper-Threading, handling four threads simultaneously. It features a base clock of 2.3 GHz and a turbo boost of up to 3.3 GHz. The defining characteristic of the 4670T is its 45 W TDP, which sits perfectly between the low-power dual-core 'T' series and the standard 84 W desktop quad-cores. This makes it an excellent choice for small form factor (SFF) builds, home theater PCs, and compact workstations that require genuine quad-core performance without generating excessive heat. It includes 6 MB of L3 cache and Intel HD 4600 integrated graphics. For users needing a balance of multi-threaded capability and thermal efficiency in a constrained space, the 4670T was a highly capable and versatile solution.
The Intel Core i5-4670T offered a rare proposition in 2013: four physical cores with a strict 45W TDP. This made it ideal for mini-ITX builds and HTPCs that needed more multi-threaded muscle than a dual-core could provide, without the heat of an 84W chip. With clocks up to 3.
3 GHz and 6MB of cache, it was highly capable. Today, it remains a decent basic PC chip but lacks modern security and efficiency features.

Architecture Overview
Utilizing the Haswell microarchitecture, the Core i5-4670T leverages Intel's 22 nm tri-gate transistors. The standout feature of Haswell is the Fully Integrated Voltage Regulator (FIVR), which moved voltage regulation onto the CPU package, resulting in cleaner power delivery and reduced motherboard component count. Unlike its dual-core siblings, the 4670T offers four physical cores, providing superior multi-threaded throughput for tasks like video encoding or light virtualization, though it lacks Hyper-Threading. The processor features 6 MB of shared L3 cache, ensuring the cores are fed with data efficiently. The integrated HD 4600 graphics feature 20 execution units, supporting basic 4K output and hardware video decoding. With a strict 45 W TDP, the architecture is tuned to prioritize sustained multi-core frequencies over peak single-core boosts. This makes the chip highly predictable in thermal output, ideal for compact chassis with limited airflow.

History
Launched in mid-2013, the Core i5-4670T addressed a specific gap in Intel's desktop lineup. While the standard 'K' series chips catered to enthusiasts and the 35 W 'T' series targeted basic SFF builds, the 4670T offered true quad-core performance in a low 45 W envelope. This was particularly appealing during a time when SteamOS and console-style living room PCs were gaining traction.
The 4670T allowed builders to create compact, console-sized PCs capable of playing contemporary games at medium settings without requiring massive coolers. It also became a staple in All-in-One designs where space and cooling are at a premium. As part of the Haswell family, it benefited from a mature 22 nm process but was eventually overshadowed by the refresh (Devil's Canyon) and the 14 nm Broadwell and Skylake generations.
Still, it remains a notable iteration in Intel's low-power desktop efforts.

Alternatives & Competitors
Should You Buy It?
Not Recommended for the right buyer
The Core i5-4670T is largely obsolete but retains niche value for budget builders repurposing old hardware. If you already own an LGA 1150 motherboard, finding a used 4670T can be a worthwhile, inexpensive upgrade from a dual-core Pentium or i3, offering true quad-core performance for basic gaming and multitasking. It is particularly attractive if you are building a low-power home server or a pfSense router, as the 45 W TDP keeps electricity costs down. However, do not build a new system around this processor. It lacks modern instructions, DDR4 support, and the single-core performance needed for modern AAA gaming. If purchasing, ensure the price is minimal. For any new build, a modern Intel Core i3 or AMD Ryzen 3 will offer significantly better performance and efficiency out of the box.
