The temperature at the inner core is about 9800 degrees F and the pressure in Earth’s inner core is about 330 to 360 gigapascals

The core-mantle boundary was just re-estimated to be about 6,600 degrees F.

“New high-resolution seismic images have produced the best estimate to date of the temperature of Earth’s extremely deep interior, researchers report.
Using a method initially developed for oil and gas exploration, the scientists studied the core-mantle boundary, a region that lies about 1,860 miles (3,000 kilometers) below the planet’s surface....”
“Reporting in tomorrow’s issue of the journal Science, the team calculated that the temperature of the region is 3,950 Kelvin, plus or minus 200.
This translates to a fiery 6,650 degrees Fahrenheit (3,677 degrees Celsius)—which is actually lower than previous predictions.”
