Old Vs. New: Six Intel Processors, Benchmarked
Budget-oriented hardware doesn’t always receive its fair share of attention. In fact, most of the time, it's pretty difficult to get samples to review from companies like Intel and AMD, which don't want to see their lower-end hardware maligned. Thankfully, many of Intel’s newer Ivy Bridge-based models are fairly affordable, starting at a dirt-cheap $35. So, we stopped into our local Micro Center retail store and bought three CPUs to create today's comparison. And we chose to pit these newest Celeron, Pentium, and Core i3 chips against former favorites that no longer get dusted off for testing.
If you've spent much time reading Tom's Hardware, then you're probably very familiar with Intel's LGA 775 interface. In fact, if you built or bought a PC between 2006 and 2008, it probably sported a Core 2 Duo or Quad CPU that dropped into LGA 775. Perhaps, like me, you constructed a gaming rig to take on 2007's big hit, Crysis. This legendary Chuck Norris of PC games convinced me that my old single-core AMD Athlon 64 FX-55 gaming rig just wasn’t going to cut it any longer. Amidst the dual- versus quad-core debates, I jumped past Intel's Conroe-based Core 2 Duo and went straight to a Core 2 Quad Q6600 (Kentsfield) with a G0 stepping. Tamely overclocked to 3.0 GHz, this CPU is still a fixture in my home, even today.
Not long after, Intel adopted 45 nm manufacturing. Once Wofldale-based processors hit the mainstream scene, it was hard to argue against a highly-overclockable Core 2 Duo E8400 for gaming. On the flip side, many power users preferred the overall performance of newer quad-core models, such as the Yorkfield-based Core 2 Quad Q9550.
Unlike AMD’s Athlon II and Phenom II families, which are still available and show up in our stories, Intel's LGA 775 platform got shoved aside in favor of newer architectures, which became the first-, second-, and third-generation Core processors. Some of our readers noticed the absence of those LGA 775-based CPUs in our tests, though, and we agree that it's time to revisit their performance in a more modern benchmark suite. So, today's story is for anyone holding on to an older Core 2 platform (or anyone who enjoys comparisons to modern offerings five years later).
Wolfdale And Yorkfield Take On Ivy Bridge
Core 2 Duo E8400 and Core 2 Quad Q9550 delivered solid clock rates right out of the box, but they're also best remembered for their substantial overclocking headroom. It was easier to keep two cores cool, so the Duos tended to handle higher voltages better, scaling higher in the process. Chips like ours, based on the E0 stepping, hit frequencies 30 to 50% higher on air cooling. So, we weren’t about to shy away from overclocking in this piece. Of course, we’ve come to expect high efficiency and per-clock performance from Intel’s Ivy Bridge-based processors, but we also know this great performance steered Intel towards locking the multiplier ratios of its lower-end offerings, a slap in the face for many enthusiasts, and a huge blow to gamers on a tight budget. Might high frequencies propel Intel’s old Core 2 architecture up beyond the latest locked-down Ivy Bridge-based chips?
Because this piece centers on data, we’re eager to hit the performance charts. But first we should introduce today’s contenders. Our trio of dual-core chips includes the Celeron G1610, Pentium G2020, and Core 2 Duo E8400. The Core i3-3225, equipped with Intel’s Hyper-Threading technology, is the oddball of the bunch, sporting two physical cores capable of addressing two threads each. It goes up against the Core 2 Quad Q9550, armed with four physical cores. As a control, we also include the quad-core Core i5-3570K, a modern enthusiast favorite and the only chip we're testing considered a worthy upgrade to the Core 2 Quad.
