Vstup procesor\u016f do maloobchodu se uskute\u010dnil na za\u010d\u00e1tku roku 2017. Co je nov\u00e9ho v t\u00e9to rodin\u011b ve srovn\u00e1n\u00ed s jej\u00edm p\u0159edch\u016fdcem? P\u0159edev\u0161\u00edm je to nov\u00e9 grafick\u00e9 j\u00e1dro \u2014 Intel UHD 630. Plus podpora technologie pam\u011bti Intel Optane (3D Xpoint), a tak\u00e9 nov\u00fd \u010dipset s\u00e9rie 200 (6. generace pracovala se s\u00e9ri\u00ed 100). A to je v\u0161e, co se opravdu zaj\u00edmav\u011b zm\u011bnilo. <\/p>\n

Coffee Lake<\/b><\/p>\n

8. generace s k\u00f3dov\u00fdm n\u00e1zvem Coffee Lake byla vyd\u00e1na na konci roku 2017. V procesorech t\u00e9to generace byly p\u0159id\u00e1ny j\u00e1dra a proporcionaln\u011b tak\u00e9 cache t\u0159et\u00ed \u00farovn\u011b, zvy\u0161ovali Turbo Boost o 200 MHz, p\u0159idali podporu DDR4-2666 (p\u0159edt\u00edm bylo DDR4-2400), ale omezili podporu DDR3. Grafick\u00e9 j\u00e1dro z\u016fstalo stejn\u00e9, ale dostalo nav\u00fd\u0161en\u00ed o 50 MHz. Za v\u0161echna zv\u00fd\u0161en\u00ed frekvenc\u00ed se muselo zaplatit zv\u00fd\u0161en\u00edm tepeln\u00fdch ztr\u00e1t na 95 watt\u016f. No a samoz\u0159ejm\u011b, nov\u00fd \u010dipset s\u00e9rie 300. Posledn\u00ed bylo zcela nepovinn\u00e9, proto\u017ee odborn\u00edci brzy dok\u00e1zali spustit tuto rodinu na \u010dipsetech s\u00e9rie 100, i kdy\u017e z\u00e1stupci Intelu tvrdili, \u017ee to nen\u00ed mo\u017en\u00e9 kv\u016fli zvl\u00e1\u0161tnostem konstrukce nap\u00e1jec\u00edch obvod\u016f. Pozd\u011bji, pravda, Intel ofici\u00e1ln\u011b p\u0159iznal, \u017ee se m\u00fdlil. Co tedy je nov\u00e9ho v 8. generaci? Fakticky v\u00edce p\u0159ipom\u00edn\u00e1 b\u011b\u017en\u00fd refresh s p\u0159id\u00e1n\u00edm jader a frekvenc\u00ed.<\/p>\n

Coffee Lake Refresh<\/b><\/p>\n

Haha! Here comes the refresh! In the fourth quarter of 2018, the 9th generation Coffee Lake processors were released, equipped with hardware protections against certain vulnerabilities like Meltdown\/Spectre. The hardware changes made to the new chips protect against Meltdown V3 and L1 Terminal Fault (L1TF Foreshadow). Modifications in software and microcode protect against Spectre V2, Meltdown V3a, and V4. Protection from Spectre V1 will still be implemented via operating system-level patches. The introduction of fixes at the die level should reduce the impact of software patches on processor performance. However, Intel only implemented this protective joy in the consumer market processors: i5-9600k, i7-9700k, i9-9900k. The rest, including server solutions, did not receive hardware protections. For the first time in the history of consumer processors, Intel's Coffee Lake Refresh supports up to 128 GB of RAM. And that's it, no more changes.<\/p>\n

So, what do we have in the dry residue? Two years of refreshes, games with cores and frequencies, plus a set of minor improvements. I really wanted to objectively evaluate and compare the performance of the main representatives of these families. Therefore, when I had a set from the seventh to the ninth generation at hand \u2014 our i7-7700 and i7-7700k were recently joined by the fresh i7-8700, i7-9700k, and i9-9900k, I took advantage of the situation and made five different Intel Core processors show what they are capable of. <\/p>\n

Testov\u00e1n\u00ed<\/b><\/p>\n

The testing involves five Intel processors: i7-7700, i7-7700k, i7-8700, i7-9700k, i9-9900k.<\/p>\n
