CPU Comparison
Intel Core i5-670 vs Intel Core i5-750
A side-by-side comparison of specs, performance and value. The Intel Core i5-670 is the highest-clocked dual-core Clarkdale desktop processor at 3.466GHz, launched in January 2010 at a premium $284 price point.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Slightly better single-threaded performance than other Clarkdales, but still completely inadequate for modern productivity.
Four cores help with basic multitasking but modern productivity apps will feel sluggish.
Gaming
Even with high clock speeds, the dual-core design cannot run modern games.
With a discrete GPU, can handle older games but cannot run modern titles at acceptable frame rates due to CPU limitations.
Virtualization
Two cores with Hyper-Threading are insufficient for meaningful virtualization.
Four real cores provide usable virtualization for lightweight VMs.
Efficiency
73W for a dual-core is acceptable for the era but poor by modern standards.
95W for four 45nm cores is inefficient by modern standards.
Specialized Performance
AI / ML
- No AI capabilities whatsoever
- Far too slow for any ML workload
- No AI acceleration instructions
- Far too slow for any ML workload
Content Creation
Gaming
- High clock speed cannot overcome dual-core bottleneck
- Integrated graphics far too weak for any 3D workload
- Was overpriced for gaming even in 2010
- Cannot run modern AAA games at playable frame rates
- With a capable discrete GPU, older titles (pre-2015) run adequately
- The 2.666GHz base clock is a significant bottleneck

Target Audience
Strengths & Weaknesses
Pros
- Highest stock clock in Clarkdale lineup
- Strong single-threaded performance for 2010
- Integrated graphics eliminate need for discrete GPU in basic builds
- 32nm process kept power at 73W despite high clocks
Cons
- Priced at $284, more than the superior quad-core i5-750
- Only two cores regardless of clock speed
- Poor value at launch and completely obsolete now
- No AVX support
- Integrated graphics too weak for any meaningful 3D work
Pros
- Four real cores provided strong 2009-era performance
- 8MB L3 cache was generous for the price
- Turbo boost significantly improved single-threaded performance
- Excellent value that redefined mainstream desktop pricing
- Overclockable via BCLK with good headroom
Cons
- No Hyper-Threading limits multi-threaded vs i7 Lynnfield
- No integrated graphics requires a discrete GPU
- 45nm process is obsolete
- No AVX instruction support
- LGA 1156 platform is dead with no upgrade path

Our Verdict on Each
At $284, the i5-670 was paradoxically more expensive than the quad-core i5-750 while offering inferior multi-threaded performance. A poor value even at launch.
Best for: Collecting unusual Intel processor SKUs
Read the full reviewA landmark processor that offered excellent quad-core value in 2009-2010. Completely obsolete today but historically significant as the processor that established the Core i5 brand.
Best for: Keeping an existing LGA 1156 Lynnfield system functional for light tasks
