hi
I have a Gaming PC with an msi 1070 gaming-x Graphics Card. I also have a sony 43x800d 4k hdr tv.
i can set 4k @ 60HZ RGB(full) 8bpc and 4k @ 60HZ 4.4.4 (limited) 8bpc in nvidia control panel with my old HDMI cable.

i want to know i need to buy new hdmi 2.0 cable? and anything will change with hdmi 2.0 cable?

unfortunately, i dont know

Cables don't have versions, that link is about HDMI devices, not cables.

actually they do as in usb 1\2 & usb 3 as usb 1\2 have 4 wires whereas usb 3 has 9.
in that link I posted above it says this.
"Cables

A standard HDMI cable.
An HDMI cable is composed of four shielded twisted pairs, with impedance of the order of 100 Ω (±15%), plus seven separate conductors. HDMI cables with Ethernet differ in that three of the separate conductors instead form an additional shielded twisted pair (with the CEC/DDC ground as a shield).[51](§HEAC-2.9)

Although no maximum length for an HDMI cable is specified, signal attenuation (dependent on the cable's construction quality and conducting materials) limits usable lengths in practice[68][69] and certification is difficult to achieve for lengths beyond 13 m.[70] HDMI 1.3 defines two cable categories: Category 1-certified cables, which have been tested at 74.5 MHz (which would include resolutions such as 720p60 and 1080i60), and Category 2-certified cables, which have been tested at 340 MHz (which would include resolutions such as 1080p60 and 2160p30).[6](§4.2.6)[62][71] Category 1 HDMI cables are marketed as "Standard" and Category 2 HDMI cables as "High Speed".[4] This labeling guideline for HDMI cables went into effect on October 17, 2008.[72][73] Category 1 and 2 cables can either meet the required parameter specifications for interpair skew, far-end crosstalk, attenuation and differential impedance, or they can meet the required nonequalized/equalized eye diagram requirements.[6](§4.2.6) A cable of about 5 meters (16 feet) can be manufactured to Category 1 specifications easily and inexpensively by using 28 AWG (0.081 mm²) conductors.[68] With better quality construction and materials, including 24 AWG (0.205 mm²) conductors, an HDMI cable can reach lengths of up to 15 meters (49 feet).[68] Many HDMI cables under 5 meters of length that were made before the HDMI 1.3 specification can work as Category 2 cables, but only Category 2-tested cables are guaranteed to work for Category 2 purposes.[74]

As of the HDMI 1.4 specification, the following cable types are defined for HDMI in general:[75][76]
Standard HDMI Cable – up to 1080i and 720p
Standard HDMI Cable with Ethernet
Standard Automotive HDMI Cable
High Speed HDMI Cable – 1080p, 4K 30 Hz, 3D and deep color
High Speed HDMI Cable with Ethernet

A third category of cable was introduced in October 2015 to certify that cables work at the 18 Gbit/s maximum bandwidth of the HDMI 2.0 specification.[77] This category tests cables at 600 MHz (2160p60 resolution), certifying them as Premium High Speed. In addition to expanding the set of cable testing requirements, the certification program introduces an EMI test to ensure cables minimize interference with wireless signals. These cables are marked with an anti-counterfeiting authentication label and are defined as:[78]
Premium High Speed HDMI Cable – 4K 60 Hz, Rec. 2020, and HDR
Premium High Speed HDMI Cable with Ethernet

In conjunction with the HDMI 2.1 specification, a fourth category of cable was announced on January 4, 2017, called "48G".[79] The cable is designed to support the 48 Gbit/s bandwidth of HDMI 2.1, supporting 4K, 5K, 8K and 10K at 120 Hz.[80] The cable is backwards compatible with the earlier HDMI devices, using existing HDMI type A, C and D connectors, and includes HDMI Ethernet.
48G Cable – 4K, 5K, 8K and 10K at 120 Hz

As of the HDMI 1.4 specification, the following cable types are defined for HDMI in general:[75][76]
Standard HDMI Cable – up to 1080i and 720p
Standard HDMI Cable with Ethernet
Standard Automotive HDMI Cable
High Speed HDMI Cable – 1080p, 4K 30 Hz, 3D and deep color
High Speed HDMI Cable with Ethernet

As I said; no versions. They do have several categories based on bandwidth ratings, but they are not tied to any particular versions of the HDMI standard. There are no "HDMI 1.3 cables" or "HDMI 1.4 cables", there are no HDMI 2.0 cables needed to operate HDMI 2.0 devices. The link you posted links specifically to the version comparison section, which has nothing to do with the different types of cables. That section only applies to HDMI devices, not cables. Cables aren't classified by version, they have a different classification system.

Any cable that labels itself as an "HDMI 2.0 cable" is automatically a non-compliant cable, as it happens; calling cables with "version numbers" has been banned by the HDMI licensing authority for this exact reason, to try to stop people from conflating HDMI cable categories with HDMI versions.

The cable categories (High Speed, Premium High Speed, etc.) are only certifications for testing at various speeds; a Premium High Speed cable has a certificate that shows it has been tested at full HDMI 2.0 speeds. However it is not necessary to have this certification, if your cable works at 4K 60 Hz then there's no need for another cable; there is no fundamental difference between HDMI cables that would require you to buy an "HDMI 2.0 cable" to work properly, since no such thing exists; hence, HDMI cables are not classified by version.

Yes, there is no need for a new cable.
