The phrase "several orders of magnitude faster" is correct and usable in written English.
It is often used to describe an increase in the speed of something. For example, "This new algorithm is several orders of magnitude faster than the previous one."
The researchers said that the actual rate of change in the magnetic orientation of the atoms they were able to measure is several orders of magnitude faster than even the new technique.
ENIAC ran continuously (in part to extend tube life), generating 150 kilowatts of heat, and could execute up to 5,000 additions per second, several orders of magnitude faster than its electromechanical predecessors.
Our algorithm runs several orders of magnitude faster.
But it's still several orders of magnitude faster than doing it yourself.
It's several orders of magnitude faster to do graphics calculations in hardware over software.
The LBM code running on one GPU was several orders of magnitude faster than Fluent with similar accuracy.
The latter extends the range of applicability of the technique to several orders-of-magnitude faster reactions but at the price of extensive computational requirements.
A reaction pathway for a classical two-species reaction is considered with one reaction that is several orders of magnitudes faster than the other.
At the end of the simulation, each biased photon packet is weighted by its likelihood ratio, which adjusts the contribution of each sample to the estimation of the Class I diffuse reflectance, so that the estimated diffuse reflectance converges towards the true value several order of magnitudes faster than using the standard Monte Carlo method.
These programs are several orders of magnitude times faster than BLAST, but they can only identify very stringent similarities that tolerate only a few mismatches and gaps.
Using the FPGA at the front end to calculate the ACF reduces the required data transfer rate by several orders of magnitude when compared to a fast framing detector.
