Intel this week launched Pentium Anniversary Edition G3258, Core i5-4690K and Core i7-4790K, all featuring unlocked clock multiplier. The Core branded parts use new Devil's Canyon core, that has several tweaks to improve its overclocking potential. For once, Intel changed Thermal Interface Material (TIM) to Next-Generation Polymer TIM, or NGPTIM. They also added more capacitors which was claimed to improve power delivery. The Pentium G3258 doesn't have Devil's Canyon enhancements, but it does have the clock multiplier unlocked, which makes it the least expensive unlocked Intel microprocessor at this time.
In many aspects the Devil's Canyon core is similar to Haswell. The i5-4690K and i7-4790K have 4 CPU cores, 6 or 8 MB last level cache, and support for DDR3-1600 memory. The processors incorporate all Haswell instruction set extensions, including TSX. With the exception of VT-d virtualization and Vpro features, and Hyper-Threading on the Core i5-4690K, the majority of Haswell technologies are also supported. Being a part of Haswell Refresh, both CPUs come with higher clock speeds. The i5-4690K runs at 3.5 GHz, or 100 MHz higher than the i5-4670K. Compared to the Core i7-4770K, the i7-4790K is 500 MHz faster. Both Devil's Canyon chips support Turbo Boost feature, and their maximum turbo frequency was increased by 100 MHz on the i5 part, and by 500 MHz on the Core i7-4790K. The i5-4690K and i7-4790K integrate HD 4600 graphics, clocked at up to 1.2 GHz and 1.25 GHz respectively. To allow higher clock speeds and better overclocking, the chips are rated at slightly higher than standard TDP, at 88 Watt. Like their Core i5 and i7 predecessors, the i5-4690K and i7-4790K are priced at $242 and $339. The CPUs should be available in stores in June.
Pentium Anniversary Edition G3258 was devised in celebration of more than 20 years of Pentium brand. The Pentium has standard features of G32xx processors, which includes 2 CPU cores, no Hyper-Threading, 3 MB L3 cache, HD graphics and support for DDR3-1333 memory. The G3258 operates at 3.2 GHz, and the on-chip HD graphics has the maximum frequency of 1.1 GHz. The Pentium Anniversary Edition is rated at 53 Watt TDP. At $72, it is only $8 more expensive than the Pentium G3240:
|Pentium G3240||2 / 2||3.1 GHz||3 MB||HD||350 / 1100 MHz||53W||$64|
|Pentium G3258||2 / 2||3.2 GHz||3 MB||HD||350 / 1100 MHz||53W||$72|
|Core i5-4670K||4 / 4||3.4 / 3.8 GHz||6 MB||HD 4600||350 / 1200 MHz||84W||$242|
|Core i5-4690K||4 / 4||3.5 / 3.9 GHz||6 MB||HD 4600||350 / 1200 MHz||88W||$242|
|Core i7-4770K||4 / 8||3.5 / 3.9 GHz||8 MB||HD 4600||350 / 1250 MHz||84W||$339|
|Core i7-4790K||4 / 8||4 / 4.4 GHz||8 MB||HD 4600||350 / 1250 MHz||88W||$339|
All processors are supported by Z97 based motherboards. The Pentium Anniversary Edition is also supported by 8-series boards.
