Testing an Engineering Sample Xeon: Did I Waste My Money? 💸

Introduction

Welcome to Tech Tested, where today we are going to delve into the question of whether buying an engineering sample Xeon E5 2695 v3 was a wise investment or a disappointing waste of money. As an avid computer hardware enthusiast, I took the plunge and purchased this engineering sample CPU through AliExpress, a popular marketplace known for its quirky hardware offerings. In this article, I will take you through my journey of exploring the performance of this engineering sample, the risks involved in buying such CPUs, and whether or not it lived up to its price-to-performance ratio. So, join me as we uncover the truth behind engineering samples and their potential in computer hardware.

Purchasing the Engineering Sample

When faced with a plethora of CPUs available on AliExpress, including various engineering samples, I decided to go for the Xeon E5 2695 v3. This particular sample caught my attention due to its attractive price-to-performance ratio. While the retail version of this CPU had a base clock of 2.3 GHz and a max turbo boost of 3.6 GHz on two cores, the engineering sample I acquired had a lower clock speed of 2.2 GHz. However, I suspected that this lower frequency indicated an early engineering sample with an unlocked multiplier, which could potentially allow for overclocking. With this speculation in mind, I went ahead and made the purchase, fully aware of the risks involved in acquiring a prototype CPU.

Understanding Engineering Samples

For those unfamiliar with engineering samples, allow me to provide a brief explanation. These CPUs are prototypes used by manufacturers to identify and fix any bugs in the platform. They also serve to determine the capabilities of the CPUs at different frequencies and loads. While some engineering samples may have unlocked multipliers, it is important to note that this is not the norm. Generally, the number of cores in a CPU influences the frequency at which it can run. CPUs with higher core counts often have lower frequencies to maintain a certain power limit. With this in mind, it becomes clear why the Xeon E5 2695 v3 engineering sample intrigued me - the potential for higher performance through overclocking.

Risks and Benefits of Buying Engineering Samples

Buying an engineering sample comes with inherent risks. As prototypes, these CPUs may have unknown flaws or limitations. Additionally, purchasing from secondhand marketplaces like AliExpress means there are no guarantees or warranties attached to the product. However, the allure of potentially owning a high-performing CPU at a fraction of the retail price is undeniably tempting. In my case, I took the leap, aware of the possible consequences, and proceeded to set up my trusty X99 test bench to put the engineering sample through its paces.

Setting Up the Test Bench

To accurately assess the performance of the Xeon E5 2695 v3 engineering sample, I utilized the ASUS X99 Deluxe motherboard. This choice was not without its peculiarities, which I will save for another discussion. Alongside the engineering sample, I had the Intel Core i7 5930K running in the system for reference. With XMP memory profiling enabled, the i7 clocked in at 3.75 GHz. To establish a baseline, I ran Cinebench R15, a CPU test I am familiar with, to compare the performance of the six-core X99 CPUs. Additionally, I ran Cinebench R23, which applies a high AVX load on the CPU, a workload expected of both the engineering sample and the i7.

Testing the CPU Performance

In Cinebench R15, the i7 5930K recorded a single-core score of 148 and a multi-core score of 1112. Turning to Cinebench R23, I obtained a single-core score of 891 and a multi-core score of 6598. These scores served as a baseline against which I would compare the performance of the Xeon engineering sample.

Overclocking Attempts

Equipped with the belief that the Xeon engineering sample had an unlocked multiplier, I ventured into overclocking territory. However, my initial attempts proved unsuccessful. Despite adjusting settings in the BIOS, including the CPU strap and core ratio, I couldn't achieve the desired overclock. This setback highlighted the risks involved when relying on engineering samples for higher performance.

Performance Comparison with the i7

Faced with the reality that the Xeon engineering sample may not be as overclockable as I had hoped, I decided to compare its performance at stock settings with that of the i7 5930K. Running CPU-Z, I observed that the Xeon was running at a fixed frequency of 2.5 GHz on all cores, which was disappointingly lower than the i7's 2.8 GHz.

Conclusion

In conclusion, my experience with the Xeon E5 2695 v3 engineering sample left me somewhat disappointed. Despite the allure of potentially unlocking greater performance, the risks involved in buying such CPUs and the limitations imposed by prototype status became apparent. Ultimately, the engineering sample fell short of my expectations, leading me to reconsider its role in my main rig. The i7 5930K, with its overclocking capabilities, remained the more reliable option for my computing needs.

Final Thoughts

As a hardware enthusiast, I must acknowledge that venturing into the world of engineering samples can be enticing. However, my experience serves as a cautionary tale for others who may be tempted by the potential for higher performance at a lower cost. When investing in computer hardware, it is crucial to weigh the risks against the benefits and choose wisely.
