About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, productivity performance, platform differences, power efficiency, pricing context, and upgrade path so you can see which CPU actually makes more sense.

Core i5-4400E

2013

Why buy it

  • +0.2% higher PassMark.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with HD Graphics 4600, while Phenom II X6 1045T needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Phenom II X6 1045T across 4 shared CPU benchmark tests.
  • Smaller total L3 cache (3 MB vs 6 MB).
  • Launch MSRP is still $266 MSRP, while Phenom II X6 1045T mostly shows up through inconsistent older-market listings.
  • 438.9% higher power demand at 512W vs 95W.

Phenom II X6 1045T

2010

Why buy it

  • Better for gaming: +5.9% higher average FPS across 4 shared CPU benchmark tests.
  • +100% larger total L3 cache (6 MB vs 3 MB).
  • Draws 95W instead of 512W, a 417W reduction.

Trade-offs

  • Lower PassMark (3,244 vs 3,251).
  • No integrated graphics, while Core i5-4400E can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i5-4400E better than Phenom II X6 1045T?
It depends on what matters more to you. For gaming, Phenom II X6 1045T is ahead with a 5.9% average FPS lead across 4 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-4400E pulls ahead with 0.2% better PassMark. Phenom II X6 1045T also has the bigger cache pool with 100% larger total L3 cache (6 MB vs 3 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-4400E is the better fit. You are getting 0.2% better PassMark, backed by 2 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-4400E is the smarter buy today. Core i5-4400E is at an unclear MSRP at $266 MSRP versus unclear MSRP, and it gives you 0.2% better PassMark. The trade-off is that Phenom II X6 1045T is still the better pure gaming CPU with a 5.9% average FPS lead across 4 shared CPU game tests in our data. It is also 100.0% better value on MSRP (12.2 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.
Which one is more future-proof for 2026 and beyond?
Core i5-4400E is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2010) and more multi-core headroom with 2 cores / 4 threads instead of 6/6. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
