Xeon E5-2667 v4 – Best Budget Gaming CPU for LGA2011-3

Xeon E5 2667 v4 is one of the most interesting processors for home use. Originally targeted at workstations, this model features a relatively high clock speed. At launch, the processor cost over $2000, and now it’s available to everyone and can be used as the foundation for a budget gaming PC.

Let’s see how good one of the highest-frequency Xeons is in 2026.

Main advantages of the model in 2026:

• Good level of single-core performance
• Solid core count with decent multi-threading
• Doesn’t drop frequency when using AVX instructions
• Affordable price

Main disadvantages:

• Aging architecture with low IPC compared to modern CPUs
• Maximum memory frequency of only 2400 MHz (though it supports quad-channel)
• You’ll need to spend money on a proper tower cooler
• Not recommended for entry-level motherboards

It’s worth noting that despite the fairly impressive TDP, real power consumption in typical tasks usually doesn’t exceed 80-100W. Although we don’t recommend using the E5 2667 v4 on very budget boards with weak VRM, the processor can still be considered relatively undemanding. Most mid-range Chinese motherboards can work with this model without problems.

Overclocking Capability

The processor has a locked multiplier, which prevents overclocking for most users. Only some branded boards from the LGA2011-3 heyday can slightly raise the bus frequency, increasing overall frequency by 3-5%, but such a minor change won’t make a meaningful difference in real-world performance.

Keep in mind that Turbo Boost Unlock is only applicable to Haswell (V3) CPUs. However, the E5-2667 v4 already runs all cores at near-maximum frequencies out of the box.

Performance and Tests

The E5-2667 v4 boasts relatively high clock speeds, which positively affect its single-core performance — a weak point of the series. Although the lag behind more modern architectures is still noticeable, the CPU performs significantly better in day-to-day tasks than high-core-count Xeons with lower clock speeds.

Gaming Performance

Its high clock speeds make it one of the best gaming options for the LGA2011-3 platform. It’s capable of delivering smooth frame rates in most esports projects, and many heavy single-player games also run quite well. The E5-2667 v4 essentially delivers the best gaming performance available among locked LGA2011-3 CPUs.

• Pre-2020 games: 95% run well (60+ FPS), 5% are playable (40-60 FPS)
• Games released between 2020 and 2026: 80% run well (60+ FPS), 10% are playable (40-60 FPS), 10% are unplayable (low FPS, stutters, micro-freezes).

Close Alternatives

High-frequency processors with 8+ cores:

• Xeon E5-1660 v4 — closest 8-core in specifications, slightly inferior in frequency and has less L3 cache
• Xeon E5-2687W v4 — 12 cores, slightly lower frequency, more demanding on motherboard VRM
• Xeon E5-2690 v4 — 14 cores, slightly lower frequency
• Xeon E5-2689 v4 — 10 cores, higher frequency, but very high TDP and price

Revisions

Besides the final version, there are also engineering versions of the E5 2667 v4. They can be distinguished by the s-spec code, which is laser-marked on the integrated heatspreader (IHS). The final version has the code SR2P5. The revision can also be determined by the HWiNFO utility.

Frequently Asked Questions

Is undervolting possible?

Voltage control is only available on QS models; it is completely locked on retail (final) CPUs.

Is there solder or thermal paste under the heat spreader?

There’s solder under the heat spreader, as with the entire Xeon E5 v3/v4 lineup.

Is the processor compatible with Win11?

No, the Xeon E5-2667 v4 is not officially supported by Windows 11, but it works fine if you bypass the CPU and TPM checks during installation.
