The AMD Phenom II X6 series offered a compelling range of six-core processors, but even within that series, distinctions existed. This comparison focuses on two processors often mentioned together: the AMD Phenom II X6 1090T (sometimes mistakenly referred to as 686) and the AMD Phenom II X6 1100T (often called 686 Plus). While there isn't an official "686 Plus," the 1100T is frequently perceived as a superior alternative. Let's delve into the specifics to understand the differences and determine which processor was the better choice.
Understanding the Nomenclature
Before we compare performance, it's vital to clear up the naming confusion. There's no official AMD processor called "Phenom II X6 686." The "686" designation is a shorthand, likely originating from online forums and communities. The actual model in question is usually the Phenom II X6 1090T. The "686 Plus" moniker, similarly informal, generally refers to the Phenom II X6 1100T. Keeping this nomenclature clarification in mind, we'll refer to them as 1090T and 1100T for clarity.
Key Differences Between the Phenom II X6 1090T and 1100T
The core difference between the 1090T and the 1100T lies in their clock speeds and TDP (Thermal Design Power). While both are six-core processors based on the same architecture, the 1100T boasts a higher clock speed.
| Feature | Phenom II X6 1090T | Phenom II X6 1100T |
|---|---|---|
| Clock Speed | 3.2 GHz | 3.3 GHz |
| TDP | 125W | 95W |
| Cache | 6MB L3 | 6MB L3 |
| Architecture | K10 | K10 |
| Manufacturing | 45nm | 45nm |
As the table shows, the 1100T has a slightly higher clock speed, resulting in marginally improved performance. The more significant difference lies in the TDP. The 1100T's lower TDP of 95W compared to the 1090T's 125W indicates significantly improved power efficiency. This lower power consumption translates to less heat generated, allowing for cooler operation and potentially quieter system fans.
Performance Implications
While the clock speed difference is relatively small, the 1100T’s higher clock speed translates to a noticeable performance increase in many applications. The improved efficiency also allows for potential overclocking opportunities, further boosting performance. Although both processors are now considered outdated by modern standards, the 1100T offered a more efficient and slightly faster experience for its time.
Benchmarking Considerations
Direct benchmarking comparisons between the two CPUs from reputable sources are challenging to find now, as both are older generation processors. However, based on the specifications and anecdotal evidence from the time of their release, the 1100T generally outperformed the 1090T in most tasks, albeit by a modest margin.
The Verdict: Which was Better?
For users in the era of these processors, the Phenom II X6 1100T (often called "686 Plus") was clearly the superior choice. Its higher clock speed and considerably lower TDP provided better performance and significantly improved power efficiency. The lower heat output also contributed to a quieter and potentially more stable system.
While both processors hold a place in PC history, the 1100T represents a refinement over the 1090T, making it the more desirable option in retrospect. Remember that both are outdated now and won't compete with modern processors, but understanding the nuances of their differences provides valuable insight into the evolution of CPU technology.
