TechSpot often take some old hardware, especially the CPU to do cross-testing, from which you can understand the hardware industry in the past few years, how much progress, very intuitive.
The protagonist is the Core i7-4770K, four generations of Haswell's flagship model, the birth of the second quarter of 2013, 22nm process, four-core eight threads, clocked at 3.5-3.9GHz, L3 cache 8MB, Core Graphics HD 4600, thermal design power 84W.
As a comparison is Core i7-8700K, eight generations of Core (Coffee Lake-S) flagship model, the third quarter of 2017 was born, 14nm process, six core twelve threads, clocked at 3.7-4.7GHz, L3 cache 12MB, Core graphics UHD 630, thermal design power 95W.
We often say that Intel likes to squeeze toothpaste, After all, toothpaste started just after four generations of Haswell, In particular, the updated Haswell Refresh, a four-generation upgrade, has simply become a new generation of product lines with the addition of lower frequencies, bringing with it new motherboards.
So four years have passed, i7-4770K is quite old or not? Especially for gamers, it should be eliminated? Test go!
This test, i7-4770K with memory DDR3-2400, bandwidth of about 29GB / s, i7-8700K with DDR4-3200, bandwidth of about 42GB / s, an increase of 45%.
i7-4770K will be overclocked to 4.6GHz run round, and i7-7700K, i5-8600K / 8400 / 7600K, etc. are also pulled for comparison.
The main graphics card using today's most high-end game card GTX 1080 Ti, and occasionally try the RX Vega 64 water-cooled version.
Resolution is 1080p, quality is generally high-end.
Of the "Singularity Ashes", which have higher CPU requirements, the 4770K can exceed 7600K, but the overclocking has almost no help and lag 8700K about 25%.
Picture quality from high to high, 4770K, 8700K gap narrowed to 17%, at the same time overclocking can draw 8400.
Crazy quality, CPU potential is fully released, 4770K only 9% slower than the latest flagship.
"Battlefield 1" also eat more CPU, 4770K is still domineering, the lowest frame rate is 96FPS, after overclocking is to reach 113FPS, draw the 7700K.
"Dawn of the Dawn 3" in the unfortunate as vice squad leader, but the minimum frame rate has reached 59 FPS, still can ensure a smooth enough, and after overclocking reached 8400 level.
By the way with RX Vega 64, Mute performance is relatively flat, but a substantial increase after overclocking, draw level 7700K.
"Kill the siege: human split" is again in the penultimate, but the frame rate is not a problem, but also improved after overclocking.
"Dust 4" situation is similar, but the basic overclocking nothing.
"Assassin's Creed: Origin" silent frequency slightly better than 7600K, improved after overclocking, the basic close to 7700K.
"Racing Plan 2" for the CPU requirements are also high, 4770K a little behind the times, but also to ensure smooth, but after the overclocking flat 8400.
