[PConline talk] A few days ago, Intel's eighth-generation Core i7-8700K and i5-8600K were officially lifted. The relevant evaluations were released for the first time. More core performance of the eighth-generation Core Duo was a qualitative leap. (Compared with the second-generation to seventh-generation toothpaste upgrades). But accordingly, their prices have actually increased a lot, plus the motherboard must match the new Z370 chipset, making the total cost of the Intel platform significantly higher.
1, Intel seven and eight generation Core specifications and prices:
In the past Intel Intel Core i7 all replaced the previous generation with the price (the second to seventh generation are basically in the 2500~2800 range), but by the eighth generation, the core and frequency have indeed improved, but the price has risen too More, i7-K rose from 2799 yuan to 3399 yuan, a full 600! However, in fact, the price of the US dollar is only only 20 US dollars more expensive, indicating that this is a substantial price increase, but in any case is a big hole! i5-K also raised the price of 400 yuan, too much.
The price increase, of course, performance is also improved, we first look at the comprehensive performance comparison chart of the first evaluation -
Referring to the above figure, Core i7-8700K performance increased by 32% compared to the 7700K, but the starting price is also more than 20%, plus the current seven-generation Core i7 prices have also been far cheaper than the starting price (boxed 2499, 2100 ) Is it a pit?
2. Eight generations of Core Duo can only be used with the expensive Z370 motherboard:
300 series motherboards currently only released the Z370, and the rest of the B360, H370 and the like will not be available until the beginning of next year. The higher-end Z390 will not be available until the middle of next year. Therefore, it is still reasonable to use the Z370 to represent the 300 series motherboard.
Every two generations of motherboard adapters is the place that Intel has been criticized by us. In the past, each generation also upgraded four PCIe 3.0 channels. The specifications are exactly the same as those of the Z270, which are 40 (24 from the motherboard and 16 from the CPU. ),...
Prices are freshly truncated today. Under the premise that the expansion capability of the motherboard has not been improved, we can see that the same positioning/postfix Z370 is more expensive than the Z270, so that the total price of installing the eight generations of Core Platforms will rise again.
3. Compare AMD platforms:
The main data is still referring to the above figure, because our first test selection of CPU is Ryzen 7 1700X, but in fact the performance of the 1800X is only about 5% stronger than the 1700X, so everyone watching the performance of the 1700X will be able to know how the 1800X performance.
Comparison shows that Ryzen 7 1700X performance slightly lost in i7-8700K (15% behind), but the price is cheaper 900, nearly 25%, not to mention the next Core i5 and Ryzen 5, so say, if and AMD In comparison, the price performance of the eighth-generation Core is really inferior.
In addition, AMD is a little cheaper on the main board. For example, the reason is the same, and it is not listed one by one.
So, if you are a player who is pursuing cost-effectiveness, in the high-end CPU product line, buying AMD platform can save a lot of money than Intel.
â—PConline evaluation room summary:
From a performance point of view, thanks to Intel's powerful process technology and chip design technology, the increase in frequency and number of cores has enabled the eighth-generation Core i7-8700K to top the most powerful processors in mainstream platforms in most application scenarios. It is the performance of the game, it is the top of the existence.
However, how do you think there is a taste of selling dogs in the inside, your processor performance is up, but the corresponding processor prices, motherboard prices have greatly increased prices, making the vast number of consumers It takes a higher cost to purchase, especially when compared to the cost-effectiveness of the AMD's Ruilong series. Intel (and perhaps the Chinese market) is not very kind. After all, U.S. prices actually only rose by 20 U.S. dollars, and the exchange rate and tax rate should not exceed 200RMB.
Coupled with the recent memory, SSD, graphics cards and the like are singing the main melody of the price increase, such a pass, the cost of installing the machine really do not know where to go, but these are nothing but Intel.
So, rationally installed, if you are not a little money, you may be able to wait for eight generations of Core Duo to cut prices or something like that, or try AMD's more cost-effective AMD platform.
