If this is a homework assignment, you really should try to answer it on your own first, otherwise the value of the reinforcement of the lesson due to actually doing the assignment will be lost on you.
The number of clock cycles per instruction in the 8085 varies between 4 and 18, so the number of instructions per clock cycle varies between 0.25 and 0.056. This does not include wait states.
The difference between 2.66 dual core processor, and 64-bit dual core processor, is really two different processor specifications. 2.66 is actually 2.66Ghz, which is the clock speed of the processor. The clock speed tells you how many times the processor can execute instructions per second. A dual core processor is a processor with two cores on one die. This can be thought of as having two processors in one. The bit specification of a processor tells you how many binary instructions a processor can execute per clock cycle. Most processors today are 32-bit (32 binary instructions per clock cycle) or 64-bit (64 binary instructions per clock cycle). More RAM can be used with a 64-bit processor. A 32-bit processor is limited to addressing 4 Gigabytes of RAM, while a 64-bit process can address (theoretically) 16 Exabytes of RAM.
Clock Speed is a measurement of the number of cycles per second of a computers synchronisation clock, measured in hertz/Hz (Millions of cycles per second) or gigahertz/GHz (billions of cycles per second).Older processors tend to perform one instruction (for example 5+3) per clock cycle. So an older 1Hz CPU could perform 1 million instructions per second.Modern processors are capable perform many instructions in a single cycle. This means that Clock Speed is generally not a very good indicator of a CPUs overall performance.
The number of MHz tells you how fast the clock is ticking in the computer, so to speak, and the clock synchronizes the processor and other things. But the processor does not necessarily perform one instruction during one clock cycle, and some instructions do more work than others. Old computers had some instructions that would take as many as 150 clock cycles, particular complex instructions to do floating point mathematics. Newer computers might do more than one instruction in one clock cycle. There are eight bit (even four bit) computers, and there are 16,32 and 64 bit computers. An operation on 64 bits in one clock cycle will do eight times as much work as the same operation on 8 bits. Some computers have operations that other computers do not have, and have to perform in software, which takes far longer.
Here is a short explanation. Clock rate or clock speed is the speed at which a microprocessor (CPU) executes instructions. Clock speeds are typically expressed in megahertz (MHz) or gigahertz ((GHz). A single clock cycle (usually shorter than a nanosecond in modern non-embedded microprocessors) toggles between a logical zero and a logical one state.

Many manufacturers publish the speed of the FSB in MHz, but often do not use the actual physical clock frequency but the theoretical effective data rate (which is commonly called megatransfers per second or MT/s). This is because the actual speed is determined by how many transfers can be performed by each clock cycle as well as by the clock frequency. For example, if a motherboard (or processor) has a FSB clocked at 200 MHz and performs 4 transfers per clock cycle, the FSB is rated at 800 MT/s.
Depending on the particular microprocessor, a machine cycle is the fetch or store of one (typically, one byte) native word. In the 8085, this is a byte fetch or store, plus the overhead in decoding and processing the instruction. In this case, the first machine cycle is four clock cycles, or T states, and subsequent machine cycles are three clock cycles, although certain instruction sequences, such as DAD, require two extra clock cycles.

Twenty two each.
In order to determine the instructions per second in an 8085 microprocessor, you need to know how long each instruction takes to execute. Some are as short as 4 T cycles. Some are as long as 18 T cycles. This is dependent on how the program is written. Add up the T cycles for each instruction. Divide the clock frequency in hertz by the number of T cycles, and you get instructions per second. Note that clock frequency is one half of the crystal frequency. Note also that you must include Twait cycles in your calculation.
