How many registers does Intel® Core™ i7-3770T Processor have?

cpu cpu-architecture

That's kind of an unusual question when evaluating an individual processor, as the number of registers is generally defined at the architectural level.

There are 16 general purpose registers in the x86-64 architecture. Could you perhaps be more specific as to your question?

I want to fetch TOP N random records from the table but not more than 2 records for same name.
```
SELECT TOP 7 Table1.ID, Table1.Name, Table1.Salary, Rnd(Abs([Table1]![id])) AS Expr1
FROM Table1
GROUP BY Table1.ID, Table1.Name, Table1.Salary, Rnd(Abs([Table1]![id]))
ORDER BY Rnd(Abs([Table1]![id]));
```
It is giving more than two records for same name. Would someone please provide some assistance.

  SIMD is an extension to the cpus since the need for sound and graphics just in case u dont know :)

  This doesn't look like T-SQL. ! is not an object delimiter and RND isn't a function in the language. Are you using SQL Server or (MS?) Access here? Please update your tags appropriately

  Can you give us a sample of the data this would be using?

  Hi PEH I am trying to achieve this in MS Access

16 registers per core?

There are also 16 SIMD registers and 8 x87 registers. The number of physical registers is also different as there are rename registers to support out-of-order execution.

@PaulA.Clayton: SIMD registers are probably only usable for SIMD instructions. In what sense are "x87 registers" non-general?
Paul A. Clayton about 8 years

@einpoklum General purpose register is a bit of a misnomer in that most ISAs (m88k being an exception) do not support FP operations in GPRs, but x87 (from what I recall) do not support memory addressing (I do not know how general the integer support was for x87 registers when used as MMX registers). (With respect to SIMD registers, the question asked about registers [I suppose one could also include various others like segment registers and flags and even MSRs.]. SSE/AVX registers support scalar FP operations (I don't know if scalar integer operations are supported.).)
Paul A. Clayton about 8 years

@einpoklum With the recent addition of gather (and scatter in Xeon Phi, if I remember correctly), SIMD registers can be used for addressing memory directly and it might be less impractical to treat SIMD registers as GPRs, though such would still be very inefficient.

Then there's the difference between architectural registers (the ones discussed so far here) and the actual hardware registers.

Thanks for code Gustav, it is giving random selection but still I am getting more than 2 records for same name...how can I use array and collection in Access..could you please help me out

If you need help integrating the code into whatever it is you're doing just let me know. It was actually sorta fun to try figure this out

Hi Taazar, its giving select * from table1 where id = 1 or Id = 2 etc also what if I have multiple columns but name shoud not more than 2
Taazar over 4 years

Umesh Yadav, Multiple columns won't affect it. It selects all the columns in the table to show, the reason ID is the only column named is because it is the only column that needs a filter.
