in any way, the 4650 is much better
these two procts are not of the same age at all
there is no comparability
first of all, like the rtx2080 / 2080tigaming OC previously released, Gigabyte geforce RTX 2070 windforce 8g is also equipped with the family's unique fengli X3 cooling system, which has a high degree of appearance recognition< Secondly, fengli 3x cooling system adopts forward and reverse 3-fan design to provide higher cooling efficiency. Fengli 3x cooling system also includes black technologies such as blade fan, new soft magnetic powder composite heat pipe, HDT heat pipe direct contact technology and semi passive intelligent cooling design, Support software tools to adjust color and light effect freely
the back of the graphics card is equipped with thick alloy armor, which has excellent protection and heat dissipation ability. Careful players will also notice that the rtx2070 cancels the nvlink interface, that is, it does not support SLI
from the previous measured results, the heat dissipation efficiency and noise control of the fengli 3x cooling system are relatively good, considering that the power consumption of the rtx2070 is lower than that of the rtx2080 / 2080ti (rtx2070 is equipped with 8pin + 6pin power supply as standard), We expect that the heat dissipation and noise control of Gigabyte geforce rtx2070 windforce 8g will be better
although nvlink is cancelled, the positioning of light flagship is unshakable
in the evaluation of rtx2080 / 2080ti, we have analyzed the new architecture of rtx20 Series in detail, so we will not repeat it here. The specification of rtx2070 continues to be simplified on the basis of rtx2080 (tu104-400 core), and uses the complete tu106-400 core. In addition to keeping the number of 64 grating units and the bandwidth of video memory unchanged, the number and frequency of stream processors are further reced to make its light flag positioning clear. In addition, the rtx2070 is about 75% of rtx2080 in terms of hardware performance of the most representative RT ray tracing unit of rtx20 series. Although there is no specific ray tracing game to play, it is expected that rtx2070 will be able to play 1080p or even 2K resolution ray tracing games
in particular, rtx2070 removes the nvlink interface of rtx2080 / 2080ti, which means it no longer supports SLI technology. We know that in the gtx10 series, NVIDIA started to cancel the SLI function from the gtx1060, while in the rtx20 series, this positioning has been adjusted again. It seems that NVIDIA thinks that players in this positioning segment will not have much demand for SLI (it may also think that the sex price ratio of double rtx2070 will threaten the sales of rtx2080...).
There is gtx970.gtx1070 on gtx770. There is no comparability between rtx2070

Rtx2070 graphics card is n card. It is a game graphics card launched by NVIDIA core AIC. It is built based on Turing architecture tu106-400 core. Its performance is better than 1070. It can use OC render
the feature of this render is fast. Using the same project and setting, the comparative test is done on gtx970 and rtx2070s respectively
RTX 2070s single frame rendering time: 3 minutes 25 seconds 205s
test results: RTX 2070s rendering speed in redshift rendering is 3 times of GTX 970 on average
the rtx2070 graphics core is equipped with tensor core and RT core, which supports deep learning supersampling and ray tracing. It has 36 groups of SM units, 2304 CUDA cores, 8GB 14gbps gddr6 video memory, 36 RT cores and 288 tensor cores
extended materials:
the application fields of hardware and software renderers are different: Hardware renderers are mainly used for real-time rendering, such as games and virtual reality. The software is mainly used for offline rendering, such as renderings and film and television level, proct level rendering. This is mainly because the hardware render is fast but not flexible, while the software render is not ideal, but it can use very complex rendering algorithm to achieve photo level reality and effect
software renderers only use the CPU's power for calculation, and usually use ray tracing method for rendering. There is no unified application standard for software renderers, but there are many general rendering algorithms, such as photon mapping, Monte Carlo, radiance and so on
RTX 2080 graphics card uses tu104-400 core and has 5944 stream processors. Core basic frequency 1710MHz, non-public 18000mhz, with 8GB 14ghz gddr6 video memory, bandwidth up to 448gb / s. In terms of TDP, the non-public standard version is 225W, while the public version is 215W
the RTX 2070 graphics card uses tu106-400 core and has 2304 stream processors. The core basic frequency is 1410mhz, the acceleration public version is 1683mhz, the non-public version is 1620mhz, with 8GB 14ghz gddr6 video memory, and the bandwidth reaches 448gb / S. in terms of TDP, the non-public standard version is 175W, and the public version is 185w
through the comparison of hardware parameters and actual test, the performance gap between them is about 20%< br />
