At their event in New York City today, Intel took the wraps off of their much-rumored 9th generation series of desktop processors.
Built upon the same "14 nm++" process technology as Coffee Lake, this new 9th generation is launching with 3 new processor models.
At the lower end, we have the i5-9600K, replacing the current i5-8600K. Staying with the same 6C/6T configuration, the 9600K improves the base frequency by 100 MHz, while adding 300 MHz to the rated single-core Turbo Boost 2.0 clock speed.
Moving onto the 8-core processors, we have the i7-9700K and the i9-9900K. Coming with Intel's first consumer i9 processor also comes the first i7 desktop processor not to feature Hyper-threading. While both processors have eight physical cores, only the i9-9900K will feature Hyper-threading allowing for a 16-thread configuration. Both processors maintain the same 95W TDP as the i7-8700K.
The lack of Hyper-Threading on the i7-9700K will provide quite the interesting performance comparison with the current flagship 6C/12T i7-8700K.
The flagship Intel Core i9-9900K has a base clock 100 MHz lower than the i7-8700K but features the same 5.0 GHz single-core Turbo Boost clock as the i7-8086K. Intel has also said that the all-core frequency for the i9-9900K is 400 MHz faster than the i7-8700K. Additionally, the i9-9900K features 16MB of cache, compared to the 12MB found on the i7-8700K.
Price-wise, both the i5-9600K and i7-9700K are similar to the 8th generation processors they are replacing, while the i9-9900K will come in at $500.
Addressing one of the most common complaints from enthusiasts about recent Intel processors, the 9th generation series of processors will come with what Intel is referring to as "Solder Thermal Interface Material" (STIM).
Switching back to solder as the TIM for these CPUs should provide significantly improved thermal conductivity, resulting in additional overclocking headroom as well as cooler and quieter operation at stock frequencies without the need of delidding.
Alongside these new processors comes the launch of a new chipset from Intel, Z390. In addition to native USB 3.1 Gen 1 (10 Gbit/s) support, Intel claims the Z390 chipset will sport improved power management for the 8-core processor variants, as well as integrated 802.11 AC connectivity.
The Z390 platform will continue to feature the same "up to 40" PCI Express lanes that we've seen for several generations, with 16 lanes being directly connected to the CPU, and the rest coming from the chipset which is still connected via a DMI 3.0 link.
Despite the launch of a new chipset in the form of Z390, these new 9th generation chipsets will maintain compatibility with all previous 300-series Intel chipsets, such as Z370 through updates that will be made available by motherboard manufacturers.
These new 9th generation processors will also feature a combination of hardware and software fixes for the following side-channel attack security vulnerabilities like Spectre and Meltdown:
- Speculative side channel variant SpectreV2 (Branch Target Injection) = Microcode + Software
- Speculative side channel variant Meltdown V3 (Rogue Data Cache Load) = Hardware
- Speculative side channel variant Meltdown V3a (Rogue System Register Read) = Microcode
- Speculative side channel variant V4 (Speculative Store Bypass) = Microcode + Software
- Speculative side channel variant L1 Terminal Fault = Hardware
While the almost $500 price tag is substantially higher than AMD's $330 8-core Ryzen 7 2700X, Intel's advantage in single-threaded performance combined with matched core counts should provide for quite the interesting comparison.
The i9-9900K is available for pre-order today, and will launch on October 19th. No word on the rest of the 9th generation lineup, but we expect them to launch at the same time as the i9 processor.
