This morning's "Tech News Digest" mentioned the impressive performance of the Core i7-8700K, but when I took a closer look, I found something odd. After examining it thoroughly, I discovered a few issues worth discussing. Today, I want to focus on one aspect.
The multi-threaded performance of the i7-8700K has made significant strides, which is quite remarkable. Both Intel and AMD rarely achieve such dramatic improvements in multi-threaded performance. This leap forward underscores the richness of Intel's technological reserves. They are clearly capable of swiftly adapting their strategies and bringing products to market that align with consumer needs.
Compared to the i7-7700K, which had four cores and eight threads, the i7-8700K now boasts six cores and twelve threads. While this may seem like a simple numerical increase, it represents much more than just additional cores and threads. Improvements in the instruction set, internal multi-core architecture, and even advancements in process technology have played crucial roles in achieving these enhancements.
When we talk about process technology, it’s worth noting that Intel has been using 14nm technology since 2015. So why is the 8th generation Core Duo still utilizing 14nm? Well, let me explain. Over the years, Intel has iterated on its 14nm process multiple times. The Kaby Lake, released last year, utilized the second-generation 14nm+ process, while the latest 8th generation processors employ the third-generation 14nm++, often referred to as 14nm++. Each iteration of this process has brought notable improvements, particularly in reducing leakage and maximizing electrical efficiency. In fact, Intel's third-generation 14nm++ process might even outperform the 10nm processes used by competitors.
However, the magic of process technology isn't without trade-offs. To keep the TDP manageable, the i7-8700K has made some compromises. One noticeable difference is the reduction in single-core performance. The i7-8700K has a base frequency of 3.8 GHz, a single-core boost of 4.7 GHz, and an all-core boost of 4.3 GHz. In comparison, the i7-7700K has a base frequency of 4.2 GHz, a single-core boost of 4.5 GHz, and an all-core boost of 4.4 GHz. These differences—400 MHz lower base frequency, 200 MHz lower single-core boost, and 100 MHz higher all-core boost—are evident in the performance metrics.
In summary, my take is that the gaming performance of the i7-8700K hasn’t changed drastically compared to the i7-7700K, and it might even perform slightly worse in single-core scenarios. However, its multi-threaded performance is a game-changer! For high-end users, the i7-8700K remains a solid choice. But for gamers or budget-conscious consumers, the i7-7700K or i7-7700 still offers excellent value, especially considering the affordable pricing of compatible motherboards.
Looking ahead, I’m particularly excited about the i5-8400, which features six cores and six threads. Whether it’s single-core or multi-core performance, it’s expected to surpass the i5-7400 by a wide margin. This processor could very well become a mainstream option in the near future. Let’s stay tuned for its release!
Ultrasonic Thermal Flowmeter uses the transmission time difference of the ultrasonic wave in the downstream and upstream medium sent and received by the ultrasonic transducer, to measure the velocity of the medium indirectly, and then calculate the flow rate through velocity.This is an indirect measurement method.
The product consists of a paired temperature sensor, Ultrasonic Flowmeter and calculator.
