Intel’s 12 P-Core Bartlett Lake CPU Fails to Beat the i9-13900K
New gaming benchmarks suggest that simply increasing the number of performance cores is no longer enough to guarantee meaningful gaming performance gains.
According to testing published by PC Games Hardware, Intel’s 2026 Bartlett Lake flagship processor, the Core 9 273PQE, failed to outperform the much older Core i9-13900K across a suite of mainstream games. Despite featuring a pure 12 P-core configuration and representing Intel’s latest architectural direction, the new chip delivered gaming results that were largely indistinguishable from a processor released four years earlier.
The results challenge a common assumption among PC enthusiasts: that more performance cores automatically translate into better gaming performance.
Instead, the benchmarks reinforce a broader reality in modern PC gaming — software optimization, scheduling behavior, and architectural maturity often matter more than raw core counts alone.
🎮 Benchmark Results Defy Expectations #
Since early leaks surrounding Intel’s Bartlett Lake lineup surfaced, many enthusiasts viewed the platform as a potential return to a “pure gaming CPU” philosophy.
Unlike Intel’s recent hybrid processors combining P-cores and E-cores, Bartlett Lake focuses entirely on performance cores, leading some users to expect substantial gains in gaming workloads.
However, the real-world results painted a different picture.
Controlled Testing Environment #
To minimize bottlenecks and maintain fair comparisons, PC Games Hardware configured both processors under closely matched conditions:
- Similar power limits (TDP)
- Comparable memory configurations
- Identical system environments
- NVIDIA RTX 5090 graphics card to eliminate GPU bottlenecks
This ensured that the benchmark results primarily reflected CPU-level gaming performance differences.
During testing:
- The Core 9 273PQE operated near 5.3 GHz
- The i9-13900K ran close to its official maximum turbo frequencies
Across 15 mainstream game titles, the results were surprisingly flat.
In most games:
- Performance differences were negligible
- Frame rates were effectively tied
- Some titles slightly favored the older i9-13900K
Despite having 12 full performance cores, the Bartlett Lake flagship failed to establish a clear gaming advantage.
⚙️ Why More P-Cores Did Not Improve Gaming Performance #
The benchmark outcome highlights an important limitation in modern game engine scaling.
Most Games Still Favor 6–8 High-Performance Cores #
The majority of modern game engines are currently optimized for approximately:
- 6 to 8 high-performance CPU cores
- Low-latency scheduling
- High clock speeds
- Strong cache efficiency
Beyond that threshold, additional cores often deliver diminishing returns.
As a result, the extra four performance cores available on the Core 9 273PQE remained largely underutilized in gaming scenarios.
This explains why the CPU’s theoretical multi-core advantage failed to translate into measurable frame-rate improvements.
Mature Optimization Matters #
Another major factor is ecosystem maturity.
The i9-13900K has existed in the market for years, giving:
- Motherboard vendors
- BIOS developers
- Game studios
- Windows scheduler updates
ample time to optimize around its architecture.
By contrast, Bartlett Lake remains a relatively new platform with less mature optimization support.
Even if the newer architecture possesses theoretical advantages, those benefits may not yet be fully reflected in current gaming workloads.
🧠 E-Cores Were Never the Main Gaming Factor #
One interesting takeaway from the results is that the i9-13900K still includes 16 efficiency cores, yet this did not negatively impact gaming performance.
This reinforces a broader understanding among enthusiasts:
- E-cores rarely provide major direct gaming gains
- Gaming workloads remain heavily dependent on fast primary threads
- High-frequency P-core performance still dominates frame-rate outcomes
Although Bartlett Lake abandons E-cores entirely, that design choice alone was not enough to produce significant gaming superiority.
🚀 Clock Speed Alone Cannot Overcome Scaling Limits #
The Core 9 273PQE reportedly supports official boost frequencies up to 5.9 GHz, though those frequencies were not consistently achieved during the published tests.
However, even if higher clocks had been maintained, the real-world gains would likely remain limited.
Modern gaming performance increasingly depends on factors such as:
- Cache hierarchy efficiency
- Memory latency
- Game engine optimization
- CPU scheduling behavior
- GPU limitations at higher resolutions
As a result, raw frequency scaling alone no longer guarantees dramatic gaming improvements.
💻 What This Means for PC Gamers #
For mainstream gamers, these benchmarks provide an important buying lesson.
Many consumers building gaming PCs fall into what enthusiasts often call “spec anxiety” — assuming that newer CPUs with higher core counts must automatically deliver superior gaming experiences.
The Bartlett Lake results strongly challenge that assumption.
Older Flagship CPUs Still Offer Excellent Gaming Value #
Even four years after release, the i9-13900K remains capable of:
- Driving flagship GPUs effectively
- Handling modern AAA titles smoothly
- Delivering high-refresh-rate gaming
- Supporting streaming and multitasking workloads
In gaming-focused systems, its real-world experience remains highly competitive with much newer hardware.
This means many users may achieve better overall value by purchasing discounted previous-generation flagship CPUs rather than paying premiums for marginal gaming gains on newer platforms.
🏭 Bartlett Lake’s Intended Market Was Never Mainstream Gaming #
Another important context point is that Bartlett Lake was reportedly designed primarily for:
- Embedded computing
- Industrial systems
- Edge computing workloads
- Specialized multi-threaded environments
It was not originally positioned as a mainstream enthusiast gaming platform.
In workloads such as:
- Heavy content creation
- Industrial parallel processing
- Virtualization
- Professional multitasking
the additional performance cores may still provide meaningful advantages.
Gaming, however, remains a comparatively narrow workload that does not scale efficiently across very high core counts.
📊 The Era of “More Cores = Better Gaming” Is Fading #
The broader implication of these benchmarks is that gaming CPU performance is entering a phase of diminishing returns.
For years, CPU marketing emphasized:
- Higher core counts
- More threads
- Larger specifications
But modern gaming engines are increasingly limited by software optimization realities rather than raw hardware scaling alone.
As a result, future gaming performance gains may depend more heavily on:
- Architectural efficiency
- Cache design
- Memory latency
- AI-assisted scheduling
- Platform optimization
rather than simply adding additional performance cores.
For gamers building PCs today, the takeaway is increasingly clear: choosing the right CPU is no longer about chasing the highest specifications on paper, but about understanding how modern games actually utilize hardware in real-world scenarios.
