NVIDIA Titan Z first test: The dual-core king of cards is terrible
|
NVIDIA's dual-core GeForce GTX Titan Z has been delayed twice in a row, and the final launch date is still undecided, which is obviously not a good sign. Previously, a manufacturer revealed to us that the first delay was due to the fact that the driver was not ready, but the most fundamental problem was that the performance was not up to standard. The madness of AMD R9 295X2 undoubtedly caught NVIDIA off guard. The power consumption of 500W is indeed ridiculously high, but it also achieved high enough performance, and because of the use of water cooling, the temperature and noise are very well controlled. As a latecomer, Titan Z is twice as expensive as others, so it must perform better in all aspects. The result is obviously not the case... NVIDIA's two delays stopped the online media, but there are still print media. The Hong Kong electronic magazine "E-Zone" published on May 8 (just before the second delay) published a detailed review article of Titan Z. According to this article, Titan Z does have two complete GK110 cores, numbered as the new GK110-350-B1, 5760 stream processors, 480 texture units, 96 ROP units, core frequency 706-876MHz, 12GB GDDR5 memory equivalent frequency 7010MHz, thermal design power consumption 375W, dual eight-pin auxiliary power supply. However, in actual use, the core frequency will be greatly accelerated automatically, and the highest frequency has even reached an astonishing 1058MHz after testing, which even exceeds the acceleration frequency of R9 295X2 1018MHz, but under normal circumstances it can only be maintained at around 900MHz. But even so, Titan Z still lost. The results of 3DMark Fire Strike Extreme, 3DMark 11 Extreme, Ungine Valley, Battlefield 4, and Sleeping Dogs are not as good as R9 295X2, lagging behind by 7.2%, 0.3%, 2.5%, and 2.2% respectively. The magnitude is not large, but this is obviously unacceptable. Batman: Arkham Origins won by 28%, but this is a consistent advantage of NVIDIA cards. Stone Giant won by 8%, but this is NVIDIA's own tessellation demonstration program. The only clean win was that Tomb Raider exceeded by 15%. E-Zone commented: Although NVIDIA has greatly optimized the acceleration frequency of GTX Titan Z, which can automatically rise to a maximum of 1058MHz during operation, it generally maintains at around 900MHz during actual operation, which is more conservative than single-core cards. The performance is also limited, so this card has no advantage in the 3DMark test, and its rival R9 295X2 is still ahead. As for 2K resolution games, the performance of GTX Titan Z is relatively better, but in fact there is no absolute advantage. The overall performance can only be regarded as being on par with R9 295X2, which is related to the imperfect driver. In terms of power consumption and temperature, the two dual-core cards are basically comparable when in standby mode. The full-load power consumption of Titan Z is significantly lower (but the system power consumption still exceeds 600W), but the temperature is not good. The two cores are as high as 82℃ and 79℃ respectively (actually acceptable), while the R9 295X2 with water cooling is only 60℃ and 62℃. No specific data is given for power consumption, but it is said that the fan noise is slightly obvious under high load. As a winner of Toutiao's Qingyun Plan and Baijiahao's Bai+ Plan, the 2019 Baidu Digital Author of the Year, the Baijiahao's Most Popular Author in the Technology Field, the 2019 Sogou Technology and Culture Author, and the 2021 Baijiahao Quarterly Influential Creator, he has won many awards, including the 2013 Sohu Best Industry Media Person, the 2015 China New Media Entrepreneurship Competition Beijing Third Place, the 2015 Guangmang Experience Award, the 2015 China New Media Entrepreneurship Competition Finals Third Place, and the 2018 Baidu Dynamic Annual Powerful Celebrity. |
